UE5.5.4 GAS - GAS Block Abilities with Tag Not Working With Parent Tags

I’m setting up tags for a Gameplay Ability and have added a parent tag (e.g., Ability.Weapon) to the ability’s Block Abilities with Tag container.

I think when this ability is active, it should block any other ability that has a matching child tag (e.g., an ability tagged with Ability.Weapon.Sword) from being activated.
But In my testing, it can’t block any Ability(except Tag is exactly matched).

Is my understanding incorrect, or is this a potential bug? I’m working in version 5.5.4.

Unfortunately the cancel abilities with tag or block abilities with tag containers does not block all child tags when a parent tag is set in it.

If I am not mistaken.

You should try making your own GA in order to make that logic.
And I also do think that logic would be quite useful if Epic did make this an update in GAS.
