Number formatted to percent doesn't stay

[SSMGroup]

I'm updating a shapefile in ArcPro.  I have a series of Double fields that represent a percentage.  (ie. 3.2 = 3.2%)

Because I want the number to display as a percent, I open the fields view and change the Number Format to "Percentage."

I save my changes, they save successfully and I see the changes.

But then after doing some joins and other process on the data, I lose my Field Alias and the Number Format I set.  Why doesn't it stay?

copy the shapefile to a featureclass in a geodatabase and try that.  I suspect that shapefiles, because of their limitations, may not support all the properties that a geodatabase can manage

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.
