This is not Airbnb itself, but the community, so for issues with payouts you need to contact Airbnb.
For pending payouts you need to check your Transaction History Page. Processed payouts show which bank account is used. Your screen shot shows there is 3rd account, which is use by default if no payout routing rules are set. You can not set the new account 4389 to the "default" as long it is not verified ("checked").
6454 can not be used for some reason. If it was used recently for a payout because it was default (or by routing rule), that payout is probably pending now (to been checked on Transaction History Page)
