Because you're doing that in a for loop that runs once for every item in the list, you're going to be constantly deleting the first issue in the list until there's nothing left. So this is expected Python behaviour and has nothing to do with the extension.

P.S.: I wouldn't name your variable list as that shadows the list built-in function.
