for the second bug, they may have been all unrated games.
Bugs?

1. I would recommend deleting all of the temporary internet files (sometimes called cache) that are stored by your browser.
2. It appears that this user has timed out in a large number of games at once, when this happens, their rating is frozen so that the members that they time out against are not shorted on their rating increases.

opera is NOT fully compatible with chess.com. opera needs to get it's javascript rendering in order :) it's a nice browser, but has too many irregularities and not enough market share for us to devote resources to it. sorry!

I usually don't mind bugs...
... except for spiders and ticks of course.
...but not Daddy Long Legs for some odd reason...
where was I?
