Marlin 2.0.x nd mks gen 13

Hi I have a homebuilt printer and have a problem with babystepping/ auto bed leveling, and fade height.I am running marlin 1.1.9bugfix and the babystepping feature does not work correctly.I tried to upgrade to marlin 2.0.X and this will not compile. I loaded my config and config.adv files into 2.0.X (So the mother board selection will be correct. MKS Gen 13) and when I tried to compile I get an “unable to compile with arduino/ramps board” error. My config file work fine on marlin 1.1.9. Any one know what gives here? Also, does any one know if the babystepping issue is fixed in 2.0.X?
Thanks
