I’ve been recording this show “Marshals” on CBS with my HDHomeRun. It works great. I record plenty of others too. But this show has been adding numbers in parenthesis after the name of the episode (see screenshot boxes in red).
Eg. “Out of the Shadows (2)”
I’m used to this when an episode is “to be continued” and has the same name. But none of these episodes have the same name.

That is how they show up on TMDB. I’ve seen that before with shows where there is a big arc that goes across 2 episodes and yet they are titled differently.
