Weird space effecting text

I have posted a couple of pictures of something weird happening with my text box. It's like there is an object with a text wrap placed on it in the area, but there is nothing there. I've checked my master pages, I've checked there there are no locked objects, I have checked that my paragraph style ragged edge is unchecked... all to no avail. I have attached a couple of pictures to show what I mean. I have even deleted everything in this area, and dragged down a new iteration from the block before, and it does the same thing. Going a bit crazy. Anybody have any idea what might be going on here?
