I created some custom item forms in v11.4.3, applied the necessary visibility requirements, and associated the form with the required Product Class value. However, since I upgraded our test environment to v11.5.1 the majority of the fields in the custom forms don’t show, even though they are not hidden or discontinued. If I remove the custom form association then the default Item form details are all shown. I also tried creating a new custom form (from the default) and, without making any changes for visibility etc, all fields are still not shown.
Is there anything I need to change/reset/correct for custom forms at v11.5?
