FM21 Editor squad numbers problem

Hi guys, I have a problem in Editor. I wanted to update squad numbers for Croatian league in editor but when I untick the bar with squad number, it disappears and I cannot change the number anymore. I tried to reinstall the editor but nothing changed. Any solution on this?
