Exporting 8k UHD project limits panel width to 4096 pixels

I’m using SBP 5.5 to create a 8K UHD project and when I export the panels using:-

File->Conformation->Export Project…


File->Conformation->Export Selected Panels…

all the panels have a width of 4096 pixels. I’m expecting the panels to have a width of 7680 pixels.

Is this a bug or limitation? Is there a way to correctly export at the camera resolution?

Do I need to log this as a bug?
