Incremental ETL not obeyed

Steps taken

1. state.json.

{
    "bookmarks": {
        "gl_accounts": {
            "ASSET": "2020-01-01T17:33:32.000000Z",
            "LIABILITY": "2020-01-01T12:31:58.000000Z",
            "EQUITY": "2020-01-01T00:00:00Z",
            "INCOME": "2020-01-01T13:53:29.000000Z",
            "EXPENSE": "2020-01-01T13:53:13.000000Z"
        },
        "gl_journal_entries": "2020-06-09T00:00:00.000000Z",
        "deposit_transactions": "2020-06-03T00:00:05.000000Z"
    }
}

2. command

tap-mambu --config tap_config.json --catalog catalog.json --state state.json | target-jsonl > state_new.json

3. The above produces my streams as json as expected
4. it also produces a new state_new.json:

{
    "bookmarks": {
        "gl_accounts": {
            "ASSET": "2021-06-17T13:23:02.000000Z",
            "LIABILITY": "2021-06-17T13:23:18.000000Z",
            "EQUITY": "2020-01-01T00:00:00Z",
            "INCOME": "2021-05-04T13:53:29.000000Z",
            "EXPENSE": "2021-05-04T13:53:13.000000Z"
        },
        "gl_journal_entries": "2021-07-01T00:00:03.000000Z",
        "deposit_transactions": "2021-07-01T00:00:03.000000Z"
    }
}

5. Rerunning the command immediately after with new state JSON file:

tap-mambu --config tap_config.json --catalog catalog.json --state state_new.json | target-jsonl > state_new_2.json

and every time after that(with the "new" state) keeps bringing back the same results all over again which results in a massive set of duplicate records.

Can you suggest what can fix the above?
