I recently installed the 757 Captain by Just Flight and all is great except one minor issue. When I try to use the autopilot for selecting manual speed it keeps rolling either up or down and if I do a single click, it rolls forward or back 3-6 knots each click. Is there a way to fix this issue to make it function where I can move one knot per mouse click like a normal add-on? It is becoming extremely annoying and difficult to fly!

Thanks in advance!
