HI, I recently upgraded to IOS 8.4 on my iphone 6. Today, two gmail emails from only one person is showing a different persons contact name. The 'new' name is actually that of another contact who has sent me emails recently, this other person is showing correctly. If I tap on the senders details it even shows this other persons mobile telephone number. It is as if somehow it thinks person 1 is person 2. When I select reply the correct contact details show. It is annoying as I could confuse who I am replying to and send the wrong email. I have deleted and reloaded the gmail account but no change. On my laptop it shows correctly.
