A Goal segmented by another Goal

Hi all,
I face a weird issue:

i can’t use the visitConvertedGoalId segementation feature for another Goal. For example: I want to see, how many people have clicked the “final purchase” button in my shop and have achieved a certain Goal before?
To do so I open the “final purchase” Goal report, and set the segment to visitConvertedGoalId==1 for example.

It would be very helpful if someone can help me with this problem.
Big thanks in advance.
Best, Dustin
