I put together a lot of doors and what we do is to apply glue to the tenon with a small brush and apply a wet coat but not enough to make it runny. Also the glue usually will squeeze out onto the panel at the corner so we do not apply glue to the last 3/4" or so. The glue will migrate a little into that area anyway once you apply some clamp pressure. Likely you may be using a bit too much glue, cut back a little and watch where you apply the glue.
I once heard that cats and women will do darn well what they please and that men and dogs would do well to accept it and just go on.
