Cast on Ele Ailment Spirit Gem Bugged I think?

Cast on Elemental Ailment doesn't recognize there is a skill gem equipped in the socket but *only* on my character. I've had to remake it 3 times so far as it seems to work for a short while before just completely breaking. I can give all 3 of the gems to a friend and they work just fine on his character but on mine it doesn't work. This is unplayable at this point due to the cost. I have to buy a new spirit gem AND a jewelers costing more than a div a pop. Please help

solved in 99% of cases by unsocketing the active spell skill and socketing it as a self cast, opening up the skill details panel, checking both weapon set boxes.

next resocketing the spell into the meta gem, opening up the skill details panel of the meta gem, ckecking both weapon set boxes, selecting the active skills in there by clicking on their respective icons at the top and making sure that both weapon sets boxes are checked.

if this doesnt work, try unsocketing other spirit gems, repeat the process and resocket those gems once you get the meta skill to work.

hope this helps, gl.
