Matinee doesn't export. Tried just everything

Sorry about that but I tried AnswerHub with no results.

we are inside my Matinee but when I try to export my movie via button… it shows me up just a general perspective camera (maybe at the origin of axis?) with enabled mouse / keyboard controls but not my specified camera. Obviously I created a director group and my camera group and changed my Level Blueprint with the three nodes (Matinee, Play, Event Play). What can I do? Thanks very much.

(vers. 4.9.10)

did you enable play on level load?
