Every circuit description you have given so far is partly contradicting the other. E.g. your latest posts tells about separate turn-on and turn-off resistors for each MOSFET, but that's impossible with the right schematic in post #4. Answering the simple question how is each MOSFET connected to gate driver(s), doe you have one or multiple drivers per bridge leg is just impossible.
Dedicated gate-source capacitors may be useful in some cases, but 10 nF is a huge value and probably increasing switching losses at lot. You didn't yet gave a motivation for it.
Also unclear is the bridge ouput wiring, cut in the post #4 schematic.
