Oh, right you are talking about the spinning logo. This is located in the slider, please go to slider revolution plugin and edit the slides, you will find it there.
Yes, it is in the slider but you were looking at the first slide when it is located in the global/static layer. This layer is always visible on every slide you create. Screenshot: http://prntscr.com/hbl6ta
