1. Renaming Date Type field changes it to Text Type

Issue: Renaming any Date type field when using "prepare form" in Adobe Pro, causes the field to be changed to a Text Type field. This causes issues with errors when uploading/downloading the form.

1. Replication Steps:
   Open the Sample Document attached in Adobe Pro
   Click Tools > Forms & Signatures > Prepare Form
   This should load the open form into the prepare form tools
   Right click on the "Date" Field
   Click 'Rename Field'
   Change the name to: Date (no "afdate" suffix)
   Hit Enter
   See in the right menu, the field has changed from a Date Type to Text Type.
   Right click the field again
   Click 'Rename Field'
   add the suffix: afdate to the field name
   Hit Enter
   See on the Right menu the field had changed back to Date Type

2. Environment:
   Windows 10 Pro
   Version 20H2
   OS Build 19042.867
   Windows Feature Experience Pack 120.2212.551.0
   Adobe Acrobat Pro DC
   Version 2021.001.20155

3. Expected Result: Date fields should remain Date Type when they are renamed

4. Observed Result: Date fields are changing field type when they are renamed to remove the "afdate" suffix
