add gallery/images style jQuery Tab

Hi,
I recently updated nextcellent-gallery and found a style bug. There is something incorrect like missing padding.

#addgallery, #uploadimage, #zipupload, #importfolder {
paddding: 10px; /* temp fix */
}

I tried to delete plugin and reinstall it.
Is that normal ?
