Deliver - not exporting all my clips?

Hey guys, I'm pretty new to video editing but been a photographer for years...

Ive really enjoying DaVinci Reslove 14 but when exporting I'm having a problem that its only exporting maybe half of my files.

I spent all day learning the software and have 36 files to export and for some reason its only exporting 20?

Ive tried it about 5 times now and I cant seem to work out why...

Any help would be great

thanks

Sam

Are you rendering in single clip mode?
