Keeps showing previous changes whilst editing

Whilst I am editing images as soon as I come back to a previous image that has edits made, it either shows auto adjustments (removing mine) or shows the previous edits before the most recents (and changes the sliders accordingly showing the date and time the last change was made). How do I turn this feature off?

I've uninstalled and re-installed the application and cannot find somehting to amend this?

Any help would be appreciated! Need to sort this urgently!
