ia.us067;MainAve_E;;;VISIBLE_HIDDEN_COLOC;ia.ia136@+MainAve_E
The '+MainAve_E' point is currently marked as a hidden point, while it's unhidden on US-67, thus causing the issue above.
The '+' just needs to be removed for the point on IA-136 and the above issue will be fixed.
======
Also the labels for US-67 along it's multiplex with IA-136 need to be corrected.
