Well... There are a couple of answers... You have a choice whether UBL is active at reset or power up. I always run my print with UBL automatically enabled. You do that by activating UBL (G29 A) and doing an M500. If you don't like that idea... You can do a G29 D followed by a M500.
For me... With UBL automatically active and alive... My startup gcode is just a G28 with nothing else. If you power up in a disabled state... You want to do a G28 followed by a G29 A.
It sounds like you have your Z_PROBE_OFFSET_FROM EXTRUDER off. You should set this number correctly. And I think you will see the nozzle start at a position that is more reasonable.
If the skirt is printing right... That is no different than what the first layer of the part prints at.... UNLESS you have raft options and such turned on. For that part of what you are seeing, it is very possible you are fighting a slicer problem.
