Cubase 8.5 w/ NI Komplete 11

I purchased NI Komplete 11 and installed it with a few hiccups. Everything seems to be running okay. However, after the install, I noticed some strange things inside CB 8.5.
For instance, when I use my sustain pedal on my keyboard, (Motif XF8), whatever the first track is in a project it mutes the track or if it’s already muted, the sustain pedal when pressed solos the track.
My thoughts were to uninstall/reinstall 8.5 but I don’t know the down side.
Any help would be appreciated.
