Hi,
I'm currently encountering an issue with labelling the grid on a circular map frame in ArcGIS Pro. Specifically, when I add labels, it only displays the outer labelling of the map grid. The problem arises when I attempt to include interior labels; it shows the interior labels both for latitude (expected) and the longitude labels which are already designated in the "Labels" option. What I'm aiming for is to apply latitude labels exclusively for interior labels.
Please refer to the attached figure to better understand the situation. I'm seeking assistance on how to remove the labelled position highlighted in the red circle.

Any insights or solutions to this problem would be greatly appreciated.
Thanks in advance!
