3D keyer not working after upgrade

I was working with studio 17 beta and the 3D keyer worked great.
Upgraded to the latest version and I get this msg.
If I re-apply the effect, it works fine but I have to re do all the settings

Is there a way to re activate the effect? (done a lot of work with it)

It was workinh fine in beta 1 & 2. But in 3 &4 the colour picker has stopped working. I can work around it by using the old method in the colour tab
