Keyboard shortcuts don't work in OSX Monterey

Just upgraded to Monterey, and the keyboard shortcuts for Pen (D key) and Empty (E key) don't work as intended; instead, pressing D brings up a prompt for dictation, and pressing E brings up the emoji window. The shortcuts for Dictation and Emoji are function+D and function+E, respectively, so It seems as if Pyxel Edit is inserting a "phantom" function keystroke when regular keys are pressed.

I've tried messing around with the OSX keyboard settings to no avail.
