I tried to clean up the mesh under the mesh menu and merged every vertex point but nothing seems to resolve the problem. Anyone any suggestion?

    Interesting! My guess is that the vertex connecting those faces was accidentally hidden at some point. Try hitting Alt+H in Edit mode and then deleting that vertex.
