Load Latent Upscale Model Node path problem in ComfUI electron

[One-With-The-Freaks]

Custom Node Testing

• I have tried disabling custom nodes and the issue persists (see how to disable custom nodes if you need help)

Expected Behavior

Using the genuine comfyui template foro hunyuan1,5 i2v, the comfy core node "Load Latent Upscale Model" should enable to choose the upscaler model via dropdown list or via arrows. This does not work.

video_hunyuan_video_1.5_720p_i2v.json

Actual Behavior

There is no way to change the genuine setting "hunyuan15_latent_upsampler_1080p,safetensors". The selector does not work, the arrows are greyed out, but clicking on an arrow changes the model name to 'undefined'. The node does not seem to find the models, although paths, filenames and data structure are correct. No upscaling will be executed.

Steps to Reproduce

see above
