It is possible that it ended up on TC's Bogons list because the prefix was listed as reserved by ARIN in:

ftp://ftp.arin.net/pub/stats/arin/delegated-arin-extended-20130730
ftp://ftp.arin.net/pub/stats/arin/delegated-arin-extended-20130731
ftp://ftp.arin.net/pub/stats/arin/delegated-arin-extended-20130801
ftp://ftp.arin.net/pub/stats/arin/delegated-arin-extended-20130802

I have not checked back further than 30 July.

It definitely shows as allocated here in whois, so I'm confused by the mismatch.

Leo
