Visibility of variables in Variable Editor on Catalog Task when navigated via New button

I want to make variables in Variable Editor isibile on Catalog Task when navigated via New button (in new mode) from related list.
I also checked the form layout and Variable Editor is included and displayed correctly when the task are created via flow but while creating manually via related list the Variable Editor is shown for few records and not for all records having Variable associated to RITM.
Can someone help me on this?
