Image Metadata Extractor does not work for some outputs

[schoenid]

Tried it with some images done with A1111 WebUI of type:

• SD1.5
• SDXL
• FLUX

Prompts, Size and Metadata output is working.

Not working is:

• cfg_scale
• steps
• clip_skip
• model_name

Example:
As the metadata further below states, data for cfg_scale, steps and model_name are available, but the output stays empty or zero (null).

raw_metadata:
