I translated this first as "in fall" and then looked at the hint which said "in the fall" so (like a dummy :) ) I, wait for it, changed it to "the fall". ERRRRRRR wrong!.
I should have known based on prior examples. :(
Either is a proper English translation, one would think.
this is a known issue that is unlikely ever to be fixed. we've been reporting it for months.
"they work in the fall and during the summer" doesnt work
