Create Township and Range as a Reference Grid Map Issue ?

I am looking at the picture here https://pro.arcgis.com/en/pro-app/latest/help/layouts/custom-grids.htm and it makes me wonder why is the map look like it is wide and it can show the township and range . On my side, I set the paper map size at 36 x48. When I add two Grids to it. One for  Township and One for Range.  The Problem is  I have is on the right side does not show labels and the left side shows it .  I have the Image in background and I think it has white collar around it.  Does that prevent the labels from showing it ?

When I resize the margin to small and narrow , it shows the labels on the right side .

Can a Reference Scale settings affect how the Labels show it on the Grid to show it or not ?

Any ideas why the wide one doesn't show it but the narrow shows it ?

Thank you for your  respond ! I figure it out why what was the cause for my right side the  labels not display.  The layer I had is a clipped from the original layer.  I went back to find the same one and is a full layer.  For example, the clipped layer was clipped from the original called PLSS and applied to our Area of Interest.  So  the original layer came from BLM. It is showed all over the USA, but I set it to Colorado only.

Now I can see all of the labels showed around nicely !
