Cannot get gitsigns keys to map properly

[synic]

I've got a similar setup to LazyVim, except I'm using <localleader>g for the prefix:

wk.register({
  ["<leader>"] = {
    b = { name = "+buffers" },
    w = { name = "+windows" },
    l = { name = "+layouts/tabs" },
    d = { name = "+debug" },
    h = { name = "+help" },
    g = { name = "+git" },
    s = { name = "+search" },
    p = { name = "+project" },
    t = { name = "+toggles" },
    u = { name = "+ui" },
    e = { name = "+diagnostis" },
    P = { name = "+plugins" },
    c = { name = "+code" },
    q = { name = "+quit" },
  },
  ["<localleader>"] = {
    g = { name = "+git" },
    gh = { name = "+hunks" },
  },
})

And then, for gitsigns:

local function gitsigns_on_attach(bufnr)
  local gs = package.loaded.gitsigns

  utils.map_keys({
    -- stylua: ignore start
    { "]h", gs.next_hunk, desc = "next hunk", buffer = bufnr },
    { "[h", gs.prev_hunk, desc = "prev hunk", buffer = bufnr },
    { "<localleader>ghs", "<cmd>Gitsigns stage_hunk<CR>", desc = "stage hunk", buffer = bufnr, modes = {"n", "v"} },
    { "<localleader>ghr", "<cmd>Gitsigns reset_hunk<CR>", desc = "reset hunk", buffer = bufnr, modes = {"n", "v"} },
    { "<localleader>ghS", gs.stage_buffer, desc = "stage buffer", buffer = bufnr },
    { "<localleader>ghu", gs.undo_stage_hunk, desc = "undo stage Hunk", buffer = bufnr },
    { "<localleader>ghR", gs.reset_buffer, desc = "reset buffer", buffer = bufnr },
    { "<localleader>ghp", gs.preview_hunk, desc = "preview hunk", buffer = bufnr },
    { "<localleader>ghb", function() gs.blame_line({ full = true }) end, desc = "blame line", buffer = bufnr },
    { "<localleader>ghd", gs.diffthis, desc = "diff this", buffer = bufnr },
    { "<localleader>ghD", function() gs.diffthis("~") end, desc = "diff this ~", buffer = bufnr },
    { "ih", "<cmd><C-U>Gitsigns select_hunk<cr>", desc = "select hunk", buffer = bufnr, modes = {"o", "x"} },
  })
end

My localleader is set to comma.

Pressing , shows +git, but pressing ,g shows h as +prefix. I've tried many permutations of the wk.register, like so:

wk.register({
  ["<leader>"] = {
    b = { name = "+buffers" },
    w = { name = "+windows" },
    l = { name = "+layouts/tabs" },
    d = { name = "+debug" },
    h = { name = "+help" },
    g = { name = "+git" },
    s = { name = "+search" },
    p = { name = "+project" },
    t = { name = "+toggles" },
    u = { name = "+ui" },
    e = { name = "+diagnostis" },
    P = { name = "+plugins" },
    c = { name = "+code" },
    q = { name = "+quit" },
  },
  ["<localleader>"] = {
    g = { name = "+git", h = { "+hunks" }},
  },
}

and

wk.register({
  ["<leader>"] = {
    b = { name = "+buffers" },
    w = { name = "+windows" },
    l = { name = "+layouts/tabs" },
    d = { name = "+debug" },
    h = { name = "+help" },
    g = { name = "+git" },
    s = { name = "+search" },
    p = { name = "+project" },
    t = { name = "+toggles" },
    u = { name = "+ui" },
    e = { name = "+diagnostis" },
    P = { name = "+plugins" },
    c = { name = "+code" },
    q = { name = "+quit" },
  },
  ["<localleader>"] = {
    g = { name = "+git" },
    gh = { name = "+hunks" },
  },
}

but nothing seems to work

This works for me:

require("which-key").register({ ["<localleader>"] = { g = { "Git", h = { "Hunks" } } } })
