Hello lee-rabs95,
Thank you for using Apple Support Communities and for sharing these details. That doesn't sound like expected behavior. Allow us to assist by recommending some troubleshooting steps you can try. To start, let's attempt the steps below:
1.) When you delete your photos, they will appear int he Recently Deleted albums. Delete them from there too and see if this unexpected behavior continues to occur.
2.) If they do return, try closing out the Photos app and then refresh things by restarting your iPhone: Restart your iPhone - Apple Support
3.) Additionally, if you have any new iOS 17 updates available, please install them. Updates do include various fixes that could help out and sort this issue out: Update your iPhone or iPad - Apple Support
If you need additional help, please reach out to Apple Support here: Get Support
