What do you mean be PE allocating 4 or 12 slots. You have 4 or 12 in the allocation rule.

Or is > it a bug? Or a feature? It depends somewhat on what else is going on. If the 4 slot jobs are shorter they might be getting in via backfill. Alternatively there might be jobs of higher priority than your 12 slot jobs eating all the reservations for other purposes. Fourthly the reservation behavior can sometimes be less than optimal when selecting where to run.
