PF2e doesnt account for proficiency in advanced weapons when treated as martial weapons via Dwarven Weapon Familiarity

[ThunderousLeft]

Dwarven Weapon Familiarity should allow my dwarf to treat Advanced Dwarven Weapons as Martial Dwarven Weapons. I have proficiency in Martial Dwarven Weapons. Yet, when using a Dwarven War Axe, a normally Advanced Dwarven Weapon, PF2e does not treat my character as proficient. This has just begun happening after porting from v10 to v11, and I have replicated it on a fresh character sheet as seen here:

Relevant REs seem to be all intact

How did you gain proficiency in martial weapons?

Everything looks in order here: your character is trained in martial dwarven weapons because they're treated as simple weapons. But an advanced dwarven weapon is treated as a martial weapon, with which the character is untrained.
