C5 Projects load skewif!

So some of my old projects are loading all messed up. It’s difficult to explain but the MIDI events appear in a arrangement above the usual one. And the Events and channels in the inspectiion bar are not alligned. Also the timeline disappears unless you drag the bottom window up to the top. As I said it’s hard to explain, it’s just so messed up. On some projects it doesn’t do this. Any ideas?
