Counting method for series

In the series overview, one film is always counted too little.
For example:

There are 24 episodes that belong to a series, but only 23 are displayed in the series overview.

Not sure exactly what you are reporting. I don’t know which of our many apps you are referring to, or what screen. If you mean one of the episode files is not being picked up, what is the show? how is the file named?

This show for example has 26 episodes in it’s first season and all of them are there.

Could be a multiple episode, meaning two of the 24 aired episodes are contained in one file
