I according to the game my Engineering is at 56 for Kul Tiran but I am unable to learn any recipes. I know it was a choice like old goblin engineering, but I am unable to even choose. I can level old school recipes and shadowlands but stuck in BFA profession hell. What do I need to do.
First off, Kul Tiran and Zandalari Engineering are not like Gnomish/Goblin Engineering. You get Kul Tiran Engineering if you are Alliance and Zandalari Engineering if you are Horde. There is no difference between the two.
Second, Are you sure the 56 is for your Kul Tiran(BfA) Engineering and not your Shadowlands Engineering? When you first open your professions tab or open the Engineering section, the top bar is only going to show your skill for the highest expansion you have trained.
Third, did you learn recipes like Rank 2 Electroshock Mount Motivator at 50 skill? If so, the next recipes the trainer has available are at 85 skill.
