It's not unique to this paper, especially on ArXiv, but it is always a sign of lazy and quantity-over-quality research when you lift a figure from another paper (LoRA) and neglect to cite that the figure is a copy from another paper.
They do cite the paper but not the figure. It seems like a small issue for such a simple one, but as someone who has worked on designing clear scientific figures, it's annoying to see this behavior.
