Some Assginment blocks not visible in Categorization schema in IC Manager

Dear All,

I am working to set up process and forms and we need to Assign process group to categorization schema. but the assignment block to assign process group to categorization schema is not visible.

I checked the configuration of ui component , it is available there? is there anything which needs to be activated in order to make that assignment block visible.

Or I tried debugging the overview pages method to see how assignment blocks are attached to it in runtime UI but I was not able to check that also any hint on this issue will be very helpful..

Regards,

Dhruvin
