Keyboard Manager - 'new editor' - keymaps toggle by themselves & change assigned shortcuts/'trigger' binds; inconsistent failure to add, edit, & delete remaps; very glitchy interface;

### Microsoft PowerToys version

0.99.1

### Installation method

Microsoft Store

### Area(s) with issue?

Keyboard Manager

### Steps to reproduce

Keyboard Manager non-functional in my case with 'new editor'.

- I am a nerd so I use an IBM model M for my job writing attached to my laptop. It has no windows key because it was produced in the late '80s.
- finally decided to try remapping. I use multiple desktops but that's a pain without a shortcut (Win + Ctrl + Left / Right)
- foolishly mapped Left Alt to Windows, but changed it back due to conflicts etc.
- mapped the Home key to Windows instead and tried adding media function to the numpad

- When testing, not all shortcuts worked. Only volume down and play/pause
- Opened the editor back up and things were randomly toggled on and off
- Also, some 'triggers' were swapped/jumbled and duplicated.

- attempting to delete these incorrect/duplicated bindings sometimes did nothing, sometimes appeared deleted until re-opening the editor, and sometimes just toggled off.
- toggling them manually made random others on the list toggle on/off

- When using the old editor, everything seems to be working fine.
- But if I change the binds on the old editor, switching back to the new editor results in bizarre errors and duplications and additions of deleted keybinds.
- switching once more to the old editor retains all of the random mistakes made by the new one
- even in the case that I deleted a keybind on the old editor, it reappeared in the new editor where i 'deleted' it, then switched back to the old editor to see it reappear again.

### Other Software

_No response_

Start by reproducing the Keyboard Manager behavior described when switching between the new and old editors, using the attached PowerToys report ZIP files for diagnostic context. Done means keymap toggles and assigned shortcuts remain consistent, and adding, editing, and deleting remaps persists after reopening or switching editors.
