You did not answer my question of why the connections were removed. Instead of actually fixing the problem you just removed the features and called it a day. Why didn’t you fix the indoor mapping if that was needed to finish the task? If you are unsure how to fix the task properly you can skip the challenge also or mark it as ‘Not an Issue’ if it’s a false positive.

As for indoor mapping, the indoor part had both indoor=yes and highway=corridor, which is a proven way to tag ways inside a shopping centre. I also loaded the ways to JOSM and I’m not getting any validator warnings about it. Could this have been a false positive from MapRoulette?
