Air plugin gui.s missing

Hi, Using MPC software on PC. When I load the MPC plugins I dont get the gui's for them just a window with red slider bars. I've had this issue since way back but just ignored the stock plugins but now I want to check out the drum synths and I can't see them properly. Any ideas?

Program edit for GUI.

I feel you. I always felt some Plugins‘ UIs were ugly or not taken care of, and some don‘t show a „proper one“ on a computer.

Following your question, on the Live 2 I just opened Mother Ducker (that‘s from Akai, though) and for the first time ever I saw it‘s GUI... wow.
