One TV episode showing alone

Server Version#: 4.34.3

Any idea on why this might be happening? Files all named correctly.

Naming is correct. The only thing I noticed was all of the other episodes were mp4 or avi. This outlier is mkv.

Added all at the same time, but they do appear all as one show in the library. So odd, it was setting off my OCD.
