Composite Applications not working after upgrade to R8.5

Hi, I have upgraded my R8 client to R8.5 however all the composite applications I had built locally no longer work. If I edit them I and try to look at the wiring I am told that I have missing properties / actions and the components show up as “empty”. However if I check the components on the palette they correctly show the actions / properties.

Anybody got any ideas on how i can resolve this? I have tried re build the comp apps without any luck.
