Your Alliance officers have probably changed your Ally AW Persistent Setup setting to “Automatically Apply Defenders to other Map Tiers” as you move UP/DOWN in Tier Difficult Map.Wording of that setting is not exactly what I said above, but that is what it acts to do.**this is a NEW SETTING as of maybe a month ago ??Supposed to help avoid cases where not everyone would place defenders in those UP/DOWN alternative maps. Although because of different Node Buffs, etc, it may or may not be best for all alliances.
