Azerite Gear not showing in BiS

When doing BiS with Raid gear and World Boss gear removed, it’s saying that 305 azerite gear is best in slot. This is very strange considering there is 340 gear out there from Mythics that are much better.

Is this a problem or is the Azerite traits really that much better with 305 gear than 340?

Most likely this is happening because of the heart of azeroth level requirements to unlock the traits. If you want to look ahead to what you would be able to unlock down the road, manually edit your heart of azeroth level to be higher, and run best in slot again.
