You are using SN74LVC1G14DBVR which is Single Schmitt-Trigger Inverter. That of course inverts the signal that comes from the MCU and Schmitt-Trigger creates a hysteresis on the PWM, which is not quite optimal. I guess that is problem nr. 1 here. I would suggest using a proper gate driver ICs to operate your MOSFETs more efficiently. I would like to see the layout, there might be other factors that severely limits your MOSFET control capabilities. Can you invite me to that project to review the layout?
