Unexpected field alias behavior when renaming field via Fields View

BB1234

ArcGIS Pro 3.1.2; mobile geodatabase standalone table

In the Fields View, if I rename a field, the field's previous name gets used as the field alias.

Why is that happening?

Esri Case #03362627 - Unexpected field alias behavior when renaming field via Fields View

These are the steps to reproduce: 

1. Create two mobile gdbs: mgdb1 and mgdb2
2. In mgdb1, create a non-spatial table with a text field: T1.
3. Copy the table to mgdb2.
4. In the table in mgdb2, delete the field alias. Save.
5. Rename the field from T1 to T2. Save.

Notes: 

• The field alias for T1 in the table in mgdb1 does not need to be delete before copying.
• The behavior only occurs if the table is copied from another mgdb. The behavior does not occur in the table in mgdb1.
• The Field table must be opened by right-clicking on the table in the Catalog > Data Design > Fields. The issue is not reproducible if the Fields table is accessed by right-clicking on the table from the Contents. This is why I was not able to reproduce originally. Opening the Fields table from the Contents would be the workaround to use until the bug is fixed.
