Validator Validation Rules fields not populated

Wappler Version : Wappler 3.9.7
Operating System : Windows
Server Model: NodeJS
Database Type: MariaDB
Hosting Type: Custom

Expected behavior

When checking Validator, Validation Rules show the Table and Column

Actual behavior

Naught, nothing, blank fields.

How to reproduce

Create a Validator step, enter the details and save. Return to Validate Options and fields are blank. Attempting to restore the values results in an Empty List notification.

As a side note, the JSON file still shows the correct entries.
