Can 30/60/90 late payments fall of early?

[DrZoidberg]

I have made a past thread about a credit card from 7 years ago that had 30/60/90 late payments in Oct/Nov/Dec of 2007 that were to fall off this year for being 7 years old. I logged into CK today and the 30 day late is off the "free credit" report that CK is offering. Just the other week I logged in and all 3 lates showed up but today the 30 day is no longer on there. 

Is this a glitch or can they fall off early?

Often the reporting agencies will remove them slightly early, in order to ensure that they are indeed off on their "expiration" date.
