Theme begins to show posts two times

Hello all together,

i have got a Problem on my Website running Karolina Theme. Since In Installed my new Gallery Plugin i hab to deactivate the dynamic loading of Content so that the gally could work. But now the Theme shows my posts to times on the Homepage. You can see it here: http://rene-springmann.de/
Also the Theme dublicates the Content on a Single Post, where a Gallery is integrated. You can find it here: http://rene-springmann.de/2014/11/herbstimpressionen-fulda-2014-bilder/ and here: http://rene-springmann.de/2014/06/ein-bisschen-hamburg-photos/

Do you have any Ideas how to Fix this?

Sorry, I forgot to post the Name of the Gallery i recently installed: Gallery Bank (3.0)

Hi!
Unfortunately, it seems like this plugin is not compatible with the theme.
