Hello everyone,

I recently started working on my first systematic review and am struggling now with the "removing duplicates" function in Mendeley. All web tutorials claim that there is a function called "Check for Duplicates" under "tools", but such a button does not exist in my programme.

Here is what I've tried so far:

- I intentionally added duplicates to check, whether the button only appears if needed

- I tried to find the button in the offline and online version

-I checked, whether the button appears under "All References", a Collection I've created and a group I've created (don't know the difference yet)

My fellow students don't have this button either and have resigned themselves to doing it manually. I would like to not do that :(

I uploaded a screenshot of the user interface.

Thanks a lot in advance!
