My landscape 8.5 x 11 layout has the map frame off-set .2 inches from the edge of the paper on all sides. However, when I export the PDF the file is exporting off-centered (see image below). It opens like this in Adobe Acrobat and prints off centered.
How it exports:

Map layout in ArcPro (not off-centered):

I am using ArcPro 2.7.1
Do I need to change some setting in the PDF - Export Layout properties pane? I export landscape 8.5 x 11 layouts all the time and have never had this issue before. I haven't changed any of the layout export properties. Something new in an update?
Edited to add:
When I export the same layout as a PNG it comes out centered correctly. When my co-worker opens the same APRX on her computer and exports the same layout as a PDF it comes out correctly.
