Possible bugs in Upfront Theme editor / builder

These are both for
Bug 1: cycling through list styles in text causes the whole page to crash. I noticed this on the Lord of the Dings site as well.
Bug 2: every time I load a page in upfront it throws up this message:
“This layout contains images that are not in your Media Library. If you plan on using those images, please import them, otherwise if you plan on replacing those images you can ignore this message.”
Even if you upload the images the message still pops up, and creates duplicates of the images in the media library.
