Try this: in the show file in folder window in parts editor right click on
select CRC SHA from the list (I think that should be standard windows and not something odd I have loaded but I'm not sure ). That should give you the sha hash of the file. Mine looks like this:
Size: 1523 bytes (0 MB)
If yours doesn't then we have different files. Mine shows up in parts editor same as in pcb i.e. 2 terminals as I expect.
Edit: We need to report a bug. I ran check for updates and it told me there were parts updates available (one of which was for the Camdenboss pcb layouts). After the update I'm now broken too ...
Edit: since I have the update log in a screen I'll file a bug report on github ...
