Incorrect behavior when editing form text fields

[MIKEB2ru 0]

Software version: Nitro Pro (12.9.1.474) x64

Operating System:        Windows 10 Pro
Architecture:        64-bit
System Memory:        7.94 ГБ
Current Locale:        Русский (Россия)

Description of the problem:
I have a PDF file in which the text fields were created using Nitro Pro 11.
These fields were created from one by copying with formatting. Their names are the same - F.
After changing the field name from F to, for example, F721, F722, F913, it does not matter, the field type is changed from Text to CheckBox. When renaming previously named fields (F12 to F920 f. e.), this problem does not occur.

If you undo the last operation, the Nitro Pro crashes.
