Yep too much paint. LOL I call it cone head. To stop this you must control the heat and the paint. Now people have their own way of doing this. I use a heat gun on high, I hold the jig by the hook just above the gun and I roll it side to side, two times. The smaller jig I do faster and bigger jig slower. I heat the jig to the point that when I put in the the paint it will cover the whole jighead without glossing over. Keep your paint stirred so it's light and fluffy. If you going to do a lot of jigs, pay or make a fluid bed. Makes a world difference. Good luck!
