Admin Forum:Edits are being misattributed

On one of the Wikis I made an edit on, my edits are not showing up under "my contributions", but instead they appear under "User:Default". Why?

The edits in question were:
 * http://kannagi.wikia.com/index.php?title=Template:Nihongo&oldid=3907
 * http://kannagi.wikia.com/index.php?title=Template:Nihongo/doc&oldid=3908
 * http://kannagi.wikia.com/index.php?title=Nagi&oldid=3909
 * http://kannagi.wikia.com/index.php?title=MediaWiki:Rollback-success&oldid=3910
 * http://kannagi.wikia.com/index.php?title=Template:Nihongo&diff=prev&oldid=3911
 * http://kannagi.wikia.com/index.php?title=Nagi&diff=prev&oldid=3913
 * http://kannagi.wikia.com/index.php?title=Nagi&diff=prev&oldid=3914

Any way to reassign them? Fei noh a  Talk 04:19, September 5, 2011 (UTC)
