Printing objects one at a time, arrange option does not take into account new slanted build plate fan and runs into other already printed objects

I'm trying to print 8 chess pieces ( all pawns ).  I set prusa slicer to print them one at a time so if one failed, the ones that had completed would be fine.  On my old MK4 that I received a year or so ago there is no problem.  The fan on the front of it is vertical.  On the upgrade from the MK3 that I just did a week or so ago, the fan is at a 45 degree angle or close to that.  This caused the fan to run into the first print making an aweful grinding sound as the fan ran into the pawn in front of it time and time again.  I think we need to have a new printer profile or something that tells prusa slicer that the clearance needed by the new MK4s is different from the MK4.
