Why Was This Rejected?

I submitted this shot of the recent eclipse and had it rejected due to:
Possible reasons:
- Non compliant use of another artist’s name.
- Undeclared Generative AI Content.
- Content not compliant with overall guidelines:
I took this and didn't label it as someone else's
Didn't use AI to create it - did use Topaz AI Sharpening tool - why should that be an issue?
Not sure what guideline this wouldn't meet.
Any clarification would be appreciated. Shutterstock and Alamy didn't have any problem accepting it.
