I have tested the customization editor feature. It’s working for me. You may check with a simple project and see if is it occurring or not.
You can create a support request along with a sample project if you think this is a bug.
Sadly no diffrences. Even with templates or a fresh created on (see vid).
Reinstallation doesn´t change anything.
After some “debugging”, I noticed that the error only happens when you right-click on the blank area on the left without having anything selected.
that means you can’t add entries (should you be able to do that with this tool? - unfortunately I don’t know much about it).
