Categories on some photos are incorrect. How are they chaned?

Hello.

Thank you for using Apple Support Communities. It sounds like you're attempting to edit or change your categories that populate within the Photos app. We'd like to help share some information with you. Within Search feature in the Photos app, you're given a few options: Moments, People, Places and Categories.

With Categories, the Photos app recognizes scenes, objects, and types of locations. This is done automatically. For more details on how this feature works, please review this resource below:

Organize and find your photos on your iPhone, iPad, or iPod touch

You'll want to see the section under "Search your photos". Categories can't be manually updated or changed. We recommend that you leave feedback here: Product Feedback

We hope this information is useful. Have a great evening.
