Adding Sort option to filter for cert_task record breaks the UI.DescriptionPlatform filter does not include the filter of the certification schedule. When you click "Run," it includes all CI's from that table. The checkboxes are not disappearing, rather the "Run" button returned all CI's, which some are not to be certified by the task (see how the total number of records changes in the list).This does not look like a problem when you click by the headers to sort. For now, avoid sorting by the filter icon, and use the headers. Searching in the header also returns all results, which is not expected behavior.Steps to Reproduce Go to the certification task record such as https://[instancename].service-now.com/nav_to.do?uri=cert_task.do?sys_id=xxxxxxxxxxxxxxxxxxxxIn the list of records to certify, click on the filter icon to expand the filter option.Click on [Add Sort]Click on [Run]Note the certification checkboxes disappear. Even if you use the left hand checkbox for the record, clicking on the green checkmark to pass or the red exclamation to fail the record has no effect.WorkaroundNo workaround available at the moment.Related Problem: PRB1413737
