Atlas content block not working properly

Haven't tested this as much, however I can confirm I am getting metamorph in my maps while i have it blocked in atlas

If you're doing Kirac missions, those are unaffected by your atlas passives.

If you're using the "Fortune Favors the Brave" craft at the map device, content it adds to the map isn't blocked because it adds a map mod which guarantees the mechanic will be present. The content blocking passives only prevent the random chance of the mechanic appearing, not modifiers that make the mechanic appear.

I took screenshots, it wasn't a kirac mission, and passive was allocated before the map was used

Okay, that covers one possibility. But:

When you were in the map, did it show a map mod along the lines of "Map contains a Metamorph encounter"?

When you put the map in the map device, did you use one of the map devices crafting options?

I did not use map device crafts, I still have them at a free use, I already checked the possibilities I could think off before posting here, including map device crafts and kirac missions, I didn't take a SS of the map mods unfortunately, but you can clearly see it's not a kirac mission and that the metamorph should be blocked via atlas, and I acctually ran Atoll earlier with metamorph in it and was confused, thought I might be mistaken, but after seeing it here yeah I am pretty certain it was suppose to be blocked

Just to add:

No I haven't used any additional consumables like scarabs or anything that can alter a map
