The 22900 entry must be a manual entry in Trulia. If it doesn't update by the end of the day, I'd delete it. There is another Trulia entry at $229,000.
Looks like the MLS price is 229,900 which was changed from 229,000 yesterday. I'm thinking that the Trulia 229000 entry is a feed from your KW.com info which still shows 229,000. Once that's changed, it may still take a few days to flow through - don't know how frequently it's updated.
