My InputTouch event only fires if the "Use Mouse For Touch" setting is enabled

Like the question says, my InputTouch event only fires when use mouse for touch setting is checked in the input section of project properties. This is what happens when I debug the blueprint

If I touch down on the screen, nothing happens. However, if I touch down and then release, both the ‘pressed’ event and ‘released’ event fire together. If I touch the screen and move my finger THEN the ‘pressed’ event fires.

When I down-click with my mouse, the ‘pressed’ event fires immediately like it should.

I am using a wacom cintiq as my touch screen with updated drivers.
