if an item is listed as timewalking firelands and 15th anniversary of wow is appearing in caverns of time

my filters:

items with both sources

@Molkree check this happen with 10 aniversary items too and already is fixed with vainilla ragnaros #293

Hm, not sure how to fix it. Probably just remove CoT from ["maps"] but will need to see how it looks on items (second source
from 15th-anniversary will stay but there's no avoiding it probably).
