Corrosion on charger area

Hello all, I have been using the Descent Mk2i since about September or so. I love the watch and it's a great dive computer too. I have zero complaints aside from the transmitter not giving me a low battery warning until 5 minutes before it stopped sending. The other issue I have had is corrosion around the charging port. This seems to start for me after 30 dives or so. I swapped out the watch and my new watch is also beginning to show signs of the same exact problem. You can see the old and the new, I am still in touch with support.
