Bass Shaker Help

Hi Guys, Im looking for help with my SIMGUB setup, i have always ran two dayton bass shakers and nobsound usb amp through simhub with no issues, i use the shakers for roadimpacts/road ruble & gear changes. i recently got a new PC and also simagic haptic reactors for my heusinkveld sprints, i set everything up as normal and added the simagic haptics aswell, I play on iRacing, Everything works fine as it should except the gear change, in sim hub when i test the bass shakers for each effect its fine and then when i test the gear change it activates the shakers but so faint you can feel nothing its almost like sound coming through them, if anyone could help it would be greatly appreciated, i have attached a snip of what my sim hub looks like
