[ SOLVED ] by removing the 'Single View Options' - Gallery & Media' in my Categories 'Display Settings' [ SOLVED ]
I'm using a Tabs setup inside a K2 article, the problem is that my Gallery & Media display twice...once in the TAB I have setup, and again under the TABS!
For example, if I click the Gallery Tab it displays OK, but underneath that TAB the exact same gallery shows up again!!
