You should not put the tip into the concentrates but put it to the side of the concentrates.
Well, because maybe your technique needs to be different. So do not put your tip into the concentrate. Put it on the side and use the side of your dab straw touch the oils. Then inhale. If you put it over the oils, and inhale its like a straw and sucks it up, from the side it can only pull the vapor. Give that a try and thanks for asking!
