Export with first few frames of the grade missing that I applied

When I send my project from FCPX 10.2.2 to Compressor 4.1.3 the first few frames are missing the colour correction I applied using Color Finale. Sometimes I can see that it's going to do it in Compressor and other times it looks like it's working but the exported video has the problem.

I even tried but 1 second of black before the video starts but it only affects the video for 1 to 2 frames.

I've attached pictures so you can see what I mean. Frame 12 has the grade applied, frame 13 doesn't and frame 14 has it again.

Has anyone else experienced this? Please help.
