Harmony 21.1 - Three Monitors, Ugee tablet (HK1560), pen displacement issues


I just bought toon boom harmony, and am trying to use it, however, I can’t even start using it with my pen tablet, because whenever I hover over it with my pen, it appears on a different screen, only moving within a small area in sync with my movement on my tablet screen. The transference of pen syncing on my other monitor, allows my pen to move roughly between the left, up to 1 quarter from the left, of my second screen, but has full up and down movement, as it would on my normal monitor.

My tablet works whilst using toon boom, but as stated above, it doesn’t sync up, and doesn’t actually allow me to interact with the program with the pen. When I am in a different program, this is not an issue.
