Touch does not work with single screen in desmume

I’m having some trouble with the desmume core and its single screen modes. Touch works fine when in top/bottom mode. Touch works oddly in bottom/top mode, while the screens are reversed the touch area remains at the bottom.

The big issue is that touch does not work at all for me when using bottom only or the quick switch options. Wondering if this is an issue localized to me or if others also experience this.
