Can't select a variable in Word processing regex for match No

If I use first result for my regex, it"s alright. But since I try to set up a different value, like all or match No, the selection of the name of variable is not selectable.
I take a screenshot of both case to show it:

Hello,
Any update to unblock the problem ?

There's an option for list, not variable in this case.
