You are confusing two different messages. The first is "name(XY) has
been referenced but does not exist". The second is "name (XY) has
been already used".

The first type can happen easily if you change your document, e.g.
remove a section. E.g run this, comment one section and run again:




Like "missing \labels" messages more runs will correct the auxiliary
files, the message will disappear in the third run. 

Your message is more serious. It means that from the point of
hyperref you have two pages with the number one. You can reproduce
it with this example:



How to correct is depends on how you are actually getting two pages
