Not saving custom preset on HD

Hi,

I have a custom preset for exporting. I set it to HD 1080p and save it (update preset). When I go back to edit screen and return to export screen it always changes it ultra hd.

The only reason I can think of would be if you have your Timeline set to UHD and not HD.

Click the preset after switching to Deliver.

The only reason I can think of would be if you have your Timeline set to UHD and not HD.

Where can I change that?

It's kind of random..if I click to edit and then straight back it shows UHD, if I click over to custom and click back to my saved setting then it shows 1080p.
