Snap fuction Problem Increment

Hello, I'm having an issue with the Snap function using Plant Layout Design. When I try to move objects along the Axis, they move in fixed value increments. I would like them to move continuously, in a freer way, not locked to specific steps. I tried changing the preferences, but I haven’t been able to fix it so far. Does anyone know how I can change this?
