Is there documentation somewhere about this? I was wondering if that was a limitation but couldn't find documentation on it. Unfortunately I'm delivering this to a client who wants the data as a shapefile.
I've tried it in ArcPro and ArcMap. I'm on the phone with technical support now, and it reproducible every time for me.
It always reverts back to the field name (instead of the alias) and numeric formatting (instead of percentage formatting) after I remove a join.
Update: This issue has now been submitted as a bug.
