Cannot move apps nor export

[Sputnik24]

I'm running Heimdall on Proxmox 8.1.3 in a LXC using bookworm debian and tteck Helper Script.

Since an update, I cannot go into edit mode to move the apps nor export. Just nothing happens when I click the edit mode button (it only points to http://url:7990. Clicking the export button (points to http://url:7990/#export) just brings me to the dashboard.

I have tested Edge Chromium and Firefox, also in private mode.

Any idea?
