That may happen if the condensate is not being drained properly due to a clogged drain hose. Though unlikely, it may also be a design flaw, in that, condensate does not flow freely towards the drain and tends to bond to the fins.

You could also try avoiding setting the A/C thermostat on its coldest all the time. Maxing the thermostat may produce condensate faster than the system can purge/drain them. I keep mine at or near the 1 o'clock/60% setting (comfort cooling).... It may be worth a try.
