I’m the leader of an alliance that voted to opt out of this next War due to a holiday in the USA and a lot being unavailable to play. I unchecked the box for war participation but each time I logged in after that, it was checked off again. The same was true for all of my coleader team (I had them check to see if the same flaw existed for them). We have a training alliance so I checked in with that leader and their coleaders and the same was true. This morning, a war was queued for both groups though both were trying to opt out. Seems the option is there but it is only cosmetic at this time.
