Analysis modes are locked in Constraints Manager

How to unlock possibility to switch on/off analysis modes? I can't change the state of the checkboxes in the Analysis Modes in Constraint Manager.
I wanted to add a rule in the constraints manager regarding minimum spacing between the outline and the pads
I can add new CSET but it is always "yellow" which means that is not "switched on". When I go to Analyze -> Analysis Modes I can't change anything.
I have looked for entry in "env" file or to run the Allegro in safe mode but no luck.
