Using a slightly lighter roast, grind finer and actually make sure your dose is bang on 15g, or grind even finer and and try 14 to 14.5g.
VST hates overdose = channeling.
As said above you need to work on your distribution.
I will go out on a limb and say where you are currently at in your journey if you are still using the 15g VST? you will be better off getting some EP precision baskets or synesso baskets and learning to dose those consistently by eye or weight. Then return to VSTs when you are in a good place.
