Bad case about janus problem

[MnKnight1]

I have tried three demos，run.sh was set as follows，
PROMPT="a cute little kitten" \ "a cute pig with a pink snout and curly tail" \ "cute small corgi"
INITIAL="kitten" \ "pig" \ "corgi"
EXP_DIR="./results"
RANDOM_SEED=0
SEMANTIC_MODEL="SD"

All of them have janus problem, I use runwayml/stable-diffusion-v1-5.why did this problem happen？Is the problem due to the use of SD rather than karlo, or is it due to incorrect 3D point cloud generation？
