Ultimate SD Upscale has strange results when using img2img_folder template

[gboxentertainment]

I've been using Ultimate SD Upscale with ControlNet as a way of upscaling on limited VRAM (as it uses tiling). It works fine on processing a single image using the example function template, but with the img2img folder example template, I get weird results where it saves outputs of each tile individually and these outputs are all just blobs of color. I've also tried turning off controlnet but still the same issue. I suspect it has something to do with the [img2img] function in the script.

I tried using multidiffusion as well for the tiled upscale rendering (Tiled Diffusion and Tiled VAE) for an img2img folder, and it seems to work well if I only have 1 file in the folder, but then if I have more than 1 file in the folder, then I get this error: "Sizes of tensors must match except in dimension 0. Expected size 768 but got size 512 for tensor number 1"
