COMFYUI - Workflow issue - Cannot choose GGUF Loader : gguf_name ... wan2.1-i2v-14b-480p-q5_k_m.gguf

[Tanpip]

I'm trying to select wan2.1-i2v-14b-480p-q5_k_m.gguf in GGUF Loader for an img2vid workflow I've grabbed

I've resolved everything else that came up as a Run error but am left with this:-

Prompt outputs failed validation:
LoaderGGUF:

• Value not in list: gguf_name: 'wan2.1-i2v-14b-480p-q5_k_m.gguf' not in []

I've put wan2.1-i2v-14b-480p-q5_k_m.gguf in the ComfyUI\models\unet folder and have the ComfyUI-GGUF node installed through the ComfyManager

I'm very very new to Comfy and have no idea if I've given enough info but if anyone can help that would be fantastic of course.

Update
I've just found a conflict in ComfyUI-GGUF i can;t seem to resolve that I'm guessing is causing the issue

【ComfyUI-GGUF】Conflicted Nodes (2)
CLIPLoaderGGUF [ComfyUI-GGUF-FantasyTalking]
UnetLoaderGGUF [ComfyUI-GGUF-FantasyTalking]

What to do.. I have uninstalled FantasyTalking from the Comfyui Manager and Restarted and no improvement

The most common reason for this is that the model is in the wrong folder maybe..
Go into your ComfyUI\models\ directory, Create a new folder named gguf if not created okay then move your wan2.1-i2v-14b-480p-q5_k_m.gguf file from the unet folder into this new ComfyUI\models\gguf folder.
After that Restart ComfyUI- completely shut it down . after relaunch do a refresh the Web UI

After these steps, click on the LoaderGGUF node in your workflow. The gguf_name dropdown should now list wan2.1-i2v-14b-480p-q5_k_m.gguf as an option.

You are currently using the standard "Load Diffusion Model" node. This node is "blind" to GGUF files (it only looks for .safetensors). That is why your file is invisible, even though it is in the correct folder.

You need to swap this node for the GGUF-specific loader.

The Fix: Switch to "Unet Loader (GGUF)"
Right-click on a blank space in your workflow.

Select Add Node > loaders > Unet Loader (GGUF) (or double-click background and search for GGUF).

In this new node, click the file list. You will now see wan2.1-i2v-14b-480p-Q4_K_S.gguf. Select it.

Important: GGUF models are already compressed, so you usually do not need the "WanBlockSwap" node.

Connect the MODEL output of your new Unet Loader (GGUF) directly to the ModelSamplingSD3 node (bypassing the BlockSwap node entirely).

If you cannot find "Unet Loader (GGUF)": You may need to install the GGUF helper nodes.

Click Manager.

Search for ComfyUI-GGUF.

Install it and Restart ComfyUI.
