Somehow every engine interprets the bones differently, your rig is alright, my exports from blender looks the same. Normally I only see the tip of the bone and in orange the next bone connected . I wish they put options to render the bones diferently but honestly i don’t think that’s gona happen.
it not only how it looked, at alsoworked bad, the pivot point was wrong, i learned which the error was. and it was choosing “Bones” option from blender, it only works for blender animation (properly) so i used weight paint, and its good now
