As I wrote, even in French, this expression is meaningless to me. Just like about 50% of what you write (if not more) because you make heavy use of regional idioms that are uncommon in Québec. I always try to communicate in international French but you obviously don't.
That is just one of many usability issues with PartDesign, unfortunately, this workbench has been orphaned for a year now. Occasionally a developer will create a commit for this workbench, but there is no longer someone dedicated to its development.
I just scanned the tracker, I didn't find any (unless it was reported in the wrong project). There's issue #3297 that you reported but it's not completely related to what's discussed here.
Sad, but true.
