Box Support for OS X Broken

tl;dr -- Box does NOT support bundle files from OS X

Early this AM I was updating a document in Numbers on Mavericks and decided I better version control it, or at least back it up somewhere. Being a business doc, I uploaded it where I keep the rest of our business docs, into Box. Or so I thought. After speaking with support, it turns out Box does NOT support bundled files, which happens to me a large majority of the files coming out of OS X. This is upsetting, I really enjoyed using Box, and really thought it would work for all my files, unfortunately that doesn't seem to be the case.
