Image rejected due to "Intellectual Property Refusal"- Looking for feedback

I appreciate your guidance on how to navigate the submission process for stock photography. I recently had a photo rejected by Adobe Stock due to "Intellectual Property Refusal," and it was taken at Blists Hill Victorian Town in Ironbridge.

I've noticed that other photos from Blists Hill Victorian Town are available on Adobe Stock, which suggests that there's a way for contributors to successfully submit content from this location. As someone who enjoys photography as a hobby and is looking to potentially offset some of the costs through stock sales, I'm eager to learn what steps are necessary.

Could you please clarify the specific requirements for obtaining property releases for commercial submissions, especially when photographing at museums or similar public (but privately owned) attractions? I'm wondering if there's a standard template for a property release form that I could use, and if museums, even volunteer-run ones, are generally accustomed to receiving such requests. Any insight into the process would be greatly appreciated.
