Boon Of Elriam Mastery Visual Indication is not there

Normally when a character gets their mastery manipulated it will be indicated with a blue icon. Square shaped one for increases and triangle shaped one for decreases.

Boon Of Elriam on Zeffo Planet increases the mastery of the characters whenever an ally uses a Special Ability, but there is no visual indication no blue icon.

Really no way to even confirm if you are even getting the said mastery increase.
