[Solved] Specify Subtitle instead of previous/next

Hi I just purchased pro and am super happy with it but I have a tiny issue that has really puzzled me, my buttons have specify subtitle instead of previous/next but only on one post. I will provide some links to show you what I mean,

As you can see the first post is messed up but the other posts are not. Even with the buttons saying specify subtitle they are still fully operational as previous/next buttons. Is there something I'm missing? Can this be fixed? Like I said it is only happening on this one post so it's not too big of an issue but I'd still like a fix if possible.

Thank you for your help and thank you for this great plugin.
