when i goto make a swap on jup with coinbase wallet i get a “close account” transaction

whenever i try to make a swap, let say sol for wif on jupiter, using coinbase wallet, when it goes to the confirm transaction screen, there is a list of about 8 transactions its trying to make me confirm all at once. there are two that are particularly catching my eye, one of them say–

“Close account”

Source: random address

Destination: my CB wallet address

Authority: my CB wallet address

does this mean its going to close my account? i dont remember seeing this in the past.

the other one that is worrying me, it actually has this transaction 3 times

and then it has the normal transaction and secondary fee transaction, which is normal. are any of these other transactions normal? i do not remember this at all when i was making transactions last year. and i certainly do not want to close my cb wallet account…

does anyone know what ComputeBudget111111111111111111111111111111 is? i have never seen this before
