Logic Pro automatically muting audio track

Hi everyone,

I've been having a problem for a while with the new version of Logic. When I have a track on which I've recorded an instrument (only the ones where I've recorded, and this happens about 30% of the time), when I press Play the track mutes itself.

There's no mute automation on the track, in my case on the video below I only have volume automation and the only solution I have to stop it muting is to bypass all the automation on the track (slightly annoying)... And no matter how many times I make a new track and put the region on it, the problem reoccurs, so it's as if there were a Mute automation IN the region and not on the track, obviously not possible... Has this already happened to any of you, and do you have a potential solution?

Here's a video example:

Sorry for my bad english I'm french..!

Thanks,

Vince.
