Themeroller - Cannot edit existing themes on the jQuery Website

Themeroller - Cannot edit existing themes on the jQuery Website

Yesterday, I was using Themeroller to create my own variation of UI lightness.

Click 'Gallery.'
Click 'Edit.'
'UI Lightness' shows up in the 'Roll Your Own' section.

Yesterday, all of the colors, attributes, etc. would appear in the menu, and I could edit them.
Now, the colors show on the Themeroller screen, but when any edits take place (e.g. Font Settings: 1.7em from 1.1em), it reverts to an all-grey theme.

I have cleared my cache, restarted my computer, and tried this on three different browsers.
I have also tried this on another computer with equally frustrating results.

Why would this work one day and not another?
Is anyone else having problems?

I have attached a screenshot.  It "shows" the correct colors on-screen and with the 'abc' example, but if you look closely, all of the colors and attributes are not the ones being shown.  For example, #aaaaaa is the border color, but the border is not grey by any means.  If you make any changes, it returns to this 'grey' coloration.
