Toolbox: Can not save custom property

Hey,

I use toolbox a lot and was very happy with it but lately i have been stuck and can not find a possible reason or cause to my problem.

I made 3 custom properties for all my toolbox components that are configuration specific.

Part No 1, Part No 2, Part No 3

I have used 1 and 2 all the time for steel and stainless steel part numbers but now i want to use part No 3.

However every time i fill in the category and want to save all the changes are deleted. Sometimes even when i simply scroll up or down the fields i just filled in are emptied.

The strange thing is that some things get saved and some categories dont.
