I'm adding tick marks and labels to my dataframe but the ticks on the top do not align with the corresponding ticks on the bottom. The same is true with left and right ticks. See image below for visual aid. I want to create a map with three adjacent dataframes but it is difficult to label efficiently if the ticks are not aligned. My best guess is this is because of the coordinate system and the fact that I'm attempting to display a curved surface in a flat box. Is this my problem or is there another solution? I'm using ArcMap 10.3.1 and the coordinate system is coordinate system is NAD 1983 UTM Zone 18N.
