Form Designer not working

I gotta say, I love this site. I was easily able to create a quote request form for my website. But whenever I try to use the new form designer, it seems to mess up my form and I have to go back to a previous version. The whole format gets messed up and the colors don't end up as I selected them. 

I think it could be a great feature, but I don't think it's quite ready for prime time, it needs a lot more testing. Thanks.
