Iphone photos now open albums

Hi folks, I was organising my iCloud photos on my iMac yesterday - just added a few more pics to a couple albums. Now when I open the iPhone camera app and click the photo thumb the photos loaded are from an album I created from 2017. Normal I open the camera app and click the bottom left corner to go to photos (most recently taken in the normal list of all photos) but now I need to specifically select ‘All Photos’ from the top right now otherwise I have the photos from the 2017 album. Anyone else seen this behaviour?
