Match 4 not give all AP

Hi,

noticed repeatedly during last days, that blast made by matching 4 tiles is not giving AP for tiles deleted by blast. Sometimes yes, sometimes not.
For example right now, played “Bullseye II” in “The Hunt - Savave Land” and during the same fight had two situations when I took care carefully:

  1. cascade, during which second match was match4 and blast deleted also 2 yellow tiles. Before cascade I had 8 yellow, but after, also 8 yellow AP. Obviously it was not working!
  2. direct match4 and row deleting blast also deleted 2 yellow tiles - before match 8 y, after match 10 yellow. Obviously it was working…

I am confused - there are any deeper rules, or the game is just bugged?

Anyone else same experience?

Are any of the tiles Crit Tiles? Crit Tiles don’t generate AP.

Of course not…
