disk first aid repeatedly finding and repairing same errors

I have a MacBook Pro 2017 13inch and yesterday evening it had a panic attack waking from sleep.

Today I ran disk first aid in recovery mode and got the following error for each snapshot.

Checking snapshot 1 of 8.

error: alloced_size (11567104) of dstream (id 1299000) does not match calculated size (11464704)

error: alloced_size (11567104) of dstream (id 1299000) does not match calculated size (11464704)

warning: snapshot fsroot tree corruptions are not repaired; they'll go away once the snapshot is deleted.

plus this error-

Error: found file extent gap

error: found file extent gap(id 1299000) at logical address 11464704+102400

Then repairs are done and the message operation successful but when I ran first aid again the exact same thing happened. This happens every time.

Can anyone tell me what the errors are and should I be making an appointment at the Genius Bar?
