GAS Abilities not being triggered by tag

I am creating a 3 piece combo system with the use of Abilities with GAS.
There are is an AM_Notifier inside the animation montages that would trigger when you can go to the text combo and am triggering the progressive combos with the use of Gameplay Tags.

But I am facing this issue where the “Heavy” combo wont go beyond the 1st combo, when it works fine with the “Light” combos.
The “Light” combos use the exact same BP as the ones shown I just have no clue on what else to look at because it just doesnt go beyond the first hit.

Also this is my first post on this forum and I will be more active through my dev career so if you guys have any advice in terms of the post quality do let me know :>

Hi @Ninjulian ,Welcome to the forums!
Could you share the Montage configuration for the Heavy and Light attacks, with the Blend Out section expanded so the values are visible?

Also, could you show the Blueprint for one of the Light combo attacks?

I’ll be waiting for your response

Edit:Additionally, could you show the contents of the ComboContainer, where you activate the ability?
