Unable to centre caption text in metaslider

Hi,

I’m running metaslider pro with vantage and have a slider on my home page (www.uninspiredramblings.com). This did have the caption centred and sitting slightly above the bottom of the image. However, today I played about with the image widths in an attempt to resolve the slightly pixelated images that I have in the metaslider. Somehow, in the process, the caption has dropped down to the bottom of the image and is no longer centred. I have tried to revert all my settings to how they were prior to my changes today, and I’ve revisited the metaslider settings, but can’t seem to resolve it… What am I doing wrong?

Thanks!
