OH28 and OH123 should be concurrent in/near Blanchester (SSW of Wilmington). It appears there are 2 hidden waypoints on OH28 between waypoints OH123_N and OH123_S which are not included on OH123.
The easiest fix would be to delete those two shaping points on OH28. Alternately the hidden waypoints could be added to OH123 between OH28/133 and OH28_W if adhering to the map is important. With a difference of 0.01 mile, it will make virtually no difference which option is selected.
