RunComfy helps you manage ComfyUI versions/models/nodes by preinstalling all models and nodes into another folder, you cannot see them from the manager and file browsers, where you see versions of the models and nodes you downloaded.
This is how we help you manage your entire ComfyUI infrastructure, so that's by design.
This does not mean that our preinstalled nodes and model/lora are not available, they are still there.
You can try adding nodes and find them there, and you can also load checkpoints to see all the models preloaded for you. See the screenshot below.
