This has happened to my Fanatic too...the only board I've had where this has happened (and I've got/had a lot) including those where I stuck the pad on myself.

My bubbles (I have several) appear when the board is warm and largely disappear in cold weather.

Have had one or two boards do this,,,small razorcut to release the air and if it's warm you might be able to stick it back down with it's own glue. If not a squirt of tarzan's grip into the hole and work it around a bit should do the job.

Just prick it with a pin. Or throw it away.

In the past - a little heat from a hairdryer and some pressure would have fixed it, but nowadays the contact adhesive has a higher tolerance to heat and it might need re-gluing. I'd steer clear of any form of silicone, hard glue (epoxy or the like).

A very small hole, syringe and some runny spray contact adhesive (take a small container to a joinery shop & they should give you some for nicks) should do the trick. Squirt it into the hole and work around the area. Some will come out the hole, so tape off - otherwise you'll be cleaning contact off your pad. Keeping in mind that it dries with contact to air (especially warm air), so by sealing it under the pad it may take a while to set. If you can keep it warm & dry, it shouldn't take too long though.

The glue has let go from the board.

Can be too: the glue staid on the board, the grip has let go from its glue up.

Happened to my fanatic as well, I put a little cut in it worked out the air and then glued it down again and put a heavy flat brick on it for 24 hrs, bubble gone.
