Nothing appears to have changed WHY did my Score go down.

So just last week an old paid collection was removed from my report. 24 hours later when I refreshed my Credit Score my Score went UP 11 pts. BUT now a week later I refresh my score again and it has gone back DOWN 10 pts. But nothing else has changed or reported. I still have the same inquiries and negative accounts. Nothing new was added. So again...why may my score have gone down?
