Validation formatting (colours) no longer working after updating criteria for one set of Format/Validation rules on a form with multiple sets of rules.

Prior to the change of one of the rules, none of the other rules will display the validation colours correctly in the form. This is an issue in both browser and smartview.

The validation itself is working as the rows with failed validations display the correct messaging, but none of the cell colouring works.
