how to fix photoset issue in tumblr?

[da animal freak]

I know it's my theme, but whenever i reblog a photoset it only leaves on half of it on and writes a big "photoset" on top of it all; pretty much ruining the post when viewed from my blog. It doesn't do this on my dashboard obviously, though. Check it out, scroll down a bit though until you see it:

any way i can just edit my current theme because i like it and dont want to change it. thanks!
