zprobe loses autolevel

I'm using Marlin on my CNC. FIX_MOUNTED_PROBE, Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN. I make the autolevel every time, over the stock, before starting to machine. Everything works correctly. The problem is that when I need to change the tool, I like to do a zprobe after the change, but if I do that, the machine loses its autolevel and starts machining always at the same level.
