Inadvertant Contact merging problems

I’m having a problem where my contacts share some information between them when they shouldn’t. For example; I start to type in a name of an email I know and the associated name of the person is someone else or vice versa - I get the name but the email address is someone elses. This problem has also extended itself to my contacts on my phone where they just seem to combine for some reason. How do I reverse this?

Thanks.

Open eM Client, go to menu Instant Messaging - Contact Pairing Assistant and press the Reset All button. Hope it helps.
