The newly added feature in beta to save custom presets in "Asset Export" does not work properly.

It only saves "x" factor scales. Other scales "Width", "Height" or "Resolution" don't save at all but are instead converted to "x" scales. So 1000px becomes 1000x.

Check out my video to showcase the issue:

This seems to be a bug.
