OSTC 5 Sacrificail Anode Bulging

Hello, Recently, I noticed that the sacrificial anode on my OSTC5 started bulging, It now makes it almost impossible to charge as it separates the charger from the computer body. I don't use my OSTC 5 as much as I would like but because the compass has never worked. (Read Here) I only use it as a backup computer on my tech dives. Nevertheless the anode has bulged.

Just for the record. After every dive on salty water I take my OSTC5 and submerge it on a recipient with fresh water and leave it there for at least 10 minutes.

What should I do? Can I get that backplate off and sand the anode?
