I encountered similar problems and reported them way back (December 2021, Carbide Motion problems and bugs (Nomad 3)). These were on a Mac, so it’s not limited to a single platform. I asked again in July this year (Revisiting Carbide Motion bugs), but sadly it seems as Carbide Motion is not a priority and bugs go unfixed for a long time.
I learned not to trust the on-screen buttons and avoid using them. I only use the keyboard. That’s probably not a great option for you on a touchscreen PC, though.
