Inserting incorrect citation

EndNote EndNote General
1

Hi there, 

EndNote seems to be inserting incorrect references into my text despite clicking on the correct one. When I right click and go to ‘edit citation’, the correct reference is there, but underneath the incorrect one. This is happening to all of my references, all randomly jumbled up. 

Any ideas?

Many thanks

what version of endnote, what operating system and have you edited any of the prior citations?  Is this an online library or desktop library as source?  Are you syncing and using different computers?  Have you called tech support?
