If your comic is Death of a Crescent Moon, I wouldn't worry about it. Your sub to view ratio isn't drastic or anything. You get less views because not all subs jump on the latest update, sometimes readers just go inactive for a while (or indefinitely).
I think what Tapas is looking out for is a title having an inordinate amount of subs within a short period of time but having very low engagement. That sort of thing is only noticeable if you suddenly have thousands of subs at once.
