Muted red audio track?

Hello.

 

I was working on this project last night and audio was working perfectly. Today I’ve re-opened the project and found out that all audio sub-clips are red and no audio is played for those sub-clips:

I’ve tried right-clicking everywhere but I’m unable to find a way to get audio back on those clips.

 

Also, if I add a new video-audio clip to the sequence, the audio is there, is only the ones I had already added those that won’t play. It wouldn’t be a problem if I didn’t had like 40 of those small clips

 

I’m a Premiere Pro noobie, so I’m not sure what I did wrong and how to fix it.

 

Please help
