List Page Display Issue

I have created a custom RC page for my client and a custom activities page part. I have a group in the Activities page called "Jobs" which is a CueGroup with a Control Action that calls the Job List page (89). For some reason, when you click that link to open the Job list, the list is initially empty. You have to change the sorting to get the records to populate. The page works perfectly if you call it from Project Accounting or if you simply run the form from the Classic Client object designer.

The page has not been modified at all and no filters are applied in properties or code.

Any suggestions? ](*,)
