Audio Player Buttons Look Weird

Hello All,

I’ve been away from my site for a while, and I just looked at it to find that my audio player buttons look strange. The play/pause button and mute buttons look like they are mixed up with some other buttons, or something like that. You can see what I’m talking about on the “Custom Song Samples” and “Song Templates” pages. Is it possible that one of the recent WordPress updates did this? Is there an easy way to fix it? Thanks a bunch; I’d really appreciate the help!

I’m using Chrome on Yosemite for Mac, if that has any bearing on the situation…
