It has been reported that after deleting a transaction, it disappears from the Transactions page once cost basis finishes recalculating, but the amount from that deleted transaction is still counted in your token balance.

While the recalculation is running, the deleted transaction may briefly reappear on the Transactions page before disappearing again.

You can upvote this forum post to indicate you are experiencing this behavior. The post status will be changed to Complete once a fix is rolled out to all users. Up-voters will be notified of the status change.
