hmm, I wonder why, they are only flat and wide in 2.1 lora though,
looks okay in 1.5 lora,
something about training in 2.1, it has happened to my other car loras as well..

do you mind sharing what model are using and text2 img settings?
and also your way of using lora, default or kohya extension

try loading through additional networks extension, tbh lot has changed and 9 months ago the extension was the only way to load loras
