double photo memories

Hello eran147,

The first thing we would suggest would be to power cycle the iPhone by following these steps found at Restart your iPhone - Apple Support:  

1. Press and hold either volume button and the side button until the power-off slider appears.

2. Drag the slider, then wait 30 seconds for your device to turn off. If your device is frozen or unresponsive, force restart your device.

3. To turn your device back on, press and hold the side button (on the right side of your iPhone) until you see the Apple logo.

While simple, this can refresh the iOS, apps and connections.

Are you seeing this with all memories, or was it only one?

Is the iPhone up to date?

This information may allow others to offer suggestions.

Cheers.
