Yes to both. The larger bubble (about 3" in diameter) occurs directly under the board's valve. This is because we cannot have drop stiching in that area. The bubble will not spread or inhibit the perfomance of the board. It is simply cosmetic.
Your board may also have groups of tiny bubbles. This is completely normal. The layers of PVC are glued together and will commonly have small areas where dust or other small particles have settled during the manufacturing process. They too will not grow or inhibit the performance of your SUP.
