Just a ground station issue.  Not a Falcon 9 issue.

2018-059A/43562 (243 km x 17863 km x 27.00°) has a delta v to GTO of  2273.9467 m/s or it is in GTO-2274
2018-059B/43563 (242 km x 17860 km x 27.00°) has a delta v to GTO of  2274.1254 m/s or it is in GTO-2074

according to my C/C++ program based on this.

EDIT: The numbers were wrong since that program didn't work well with sub-sync orbits.

I'v now Updated the numbers with the program you can find here: https://forum.nasaspaceflight.com/index.php?topic=43465.msg1839907#msg1839907
