I have the same problem and send a massage to Black magic. I got the following answer “The new Final Cut Pro is a complete rewrite of the software, and because of this, not all the features that we need are present int he first release. Blackmagic Design and Apple are working very closely to improve compatibility and to iron out any compatibility issues etc. We appreciate your patience while we work to improve coherence between the Final Cut software and our products.”
So must wait till the following upgrade.
