Midi Remote Problem with Lemur or Touch OSC

Hello! I’m trying to use Lemur or Touch OSC to create a custom midi remote template but every time I map 3 or more buttons to basic functions I get this crazy loop that causes the buttons to flicker on and off, rendering my Cubase session useless. I’ve tried Lemur and Touch OSC, checked all the settings and the problem persists. Am I missing something? IS this a bug?
