Heatmap Cut Off When Printing to PDF

[AbigailEbelherr]

I've created a heatmap of car crashes in ArcGIS Pro and am now attempting to print my map to a PDF document. However, the right side of the heatmap data keeps getting squared off. I attached a screenshot of what it looks like in Arc Pro and the PDF.

This is when I use the Microsoft Print to PDF option. When I use the Adobe PDF, it cuts off an even larger chunk.

I tried exporting as an emf and then converting to an png as I had seen some other threads suggest that. The quality of the PNG ends up terrible if I use that method. I would like to know if I could fix this so I can just print directly to PDF and keep my heatmap.

Any resolution for this? I am having the same issue with my maps. Seems to be some kind of invisible boundary.
