In the library I have only the first series

The folders are as follows:
Star Trek

  • Season 1
    – S01E01
    – S01E02
    –…
  • Season 2
    – S02E01
    – S02E02
    –…

S01E01 adds the system to the library but does not add S02E01. For all the serials I have on HDD, OSMC always adds only the first series.

I know the page and read it. But not really. I had one thing wrong in setup.
