Cursor position misaligned on screen in Route Planner

[TMac 4]

While adjusting settings in the route planner, on the left side panel, the position of the hand cursor and the area highlighted on the screen became misaligned. The option one above the cursor position was selected. This meant, while trying to click on the "Waypoints" heading, it actually clicked on the "Delete Route" heading. You can see in the screen shot, that the highlighted area of the screen is one option above where the hand cursor is. I tried to repeat this after closing the screen and I could not - it is now behaving normally. I have a video of this, but I could not upload a video.
