"I would assume that you have checked the height of the little key that opens over the A# - if this does not open far enough, this can make the A# pitch too sharp. There may also be a build up in the tone hole so it should be checked and cleaned."
If the venting of the top joint Bb tonehole (the small pad cup immediately above the LH3 fingerplate) is too low or the tonehole is occluded, then that will cause it to be stuffy or flat rather than sharp.
If the Bb is too sharp (in both registers) and all the other notes speak easily over the entire range, then the top joint Bb tonehole may have been enlarged for whatever reason which has thrown this note out of tune.
If that is the case, then removing the top joint main action keys and filling in the Bb tonehole with wax to bring it down to pitch is your best option. You can add more wax until it's brought down to pitch or if you've added too much and it's too flat, then remove some to bring it into tune.
Use a heated metal rod (a spare rod screw will do) to apply and shape the wax to retain a round tonehole, but having more of the wax on the top side of the tonehole to effectively move the tonehole lower down the top joint and further away from the reed.
Only fill in the top part of the tonehole and don't go into the uncdercutting. If you get any wax on the flat recess around the tonehole (inside the rim), then scrape that out with a toothpick or an old clarinet reed with the tip cut square so it won't scratch or chip the wood.
