Custom tools disappearing from Library

Every time I make a new tool, it is gone from the Library next time I open Carbide Create. Running Windows10 on a new machine. Currently using build 400 of CC.

Any Ideas?

Seems to be a bug and persistent through 403 available at: https://carbide3d.com/carbidecreate/unstable/ — it’s reported and hopefully will be fixed presently.

I have the same problem on Mac it started on v400 I’m on 403 now same thing…

The Elements library is also blacked out
