TV Series Year range

Hi there! How do we change the year range of a tv series? There's a few shows that are listed as ending, but that is not the case.

This one has been renewed to a fifth season next year, so is not ending in 2021.

And this one is listed as ended, bit the third season premiered today, so it's likely that will be around longer too.

I hope this helps.
