Wrong counters in series listings?

This is what i see in my list of series in nzbdrone for this specific show:

Why is the total of episodes zero ?
There are more than that (detail episodes in nzbdrone) :

I agree that the episode in season 2 isn’t counted, but why are the episodes of season 1 not in the total ?
I should have 0/13.

Same situation (season 1 unmonitored) but here the total is ok :

It’s 0 because all the episodes are unmonitored. So nzbdrone concludes you don’t want them, and thus keeps them out of the count.
With the other example drone includes them, coz you obviously already have the episodes.
