Sequence I worked on 2 days ago with multiple clips now only has one single clip

I saved that sequence when I exported the video of it on Tuesday and now its gone, replaced by a "Sequence"that is basically an export of the video, which is useless to me. The way I see it now I have to go back to my Master Edit sequence and pull out and cut the bits I need from there, which means another 2 hours of work for me. Premiere Pro almost pulled the same thing to me earlier with that Master Edit when I opened it, and I had to quit without saving to load the Master Edit sequence with multiple clips. What is Premiere doing that makes it turn all my edited sequences into practically useless exports and how can I stop it. This is the second project it does this to and its driving me up a wall.

Ive attached pictures of both the Master Edit sequence and the culprit sequence, as well as a screenshot of my entire project premiere window. P.S. I turned off track targeting on multiple tracks and source patching, in case that may have been the culprit.
