Kitchenaid KF8 Drip tray

I have been using my KF8 for about two weeks now and the drinks have been fantastic. The machine rinses itself whenever I start the machine and I turn it off. I normally put a cup under the spout to collect all the rinse water. Just recently I started noticing that my drip tray fills with water and that I need to empty it after maybe 8-10 drinks. It seems like a little water drips into the tray with every drink I make. The pucks are looking solid and the drinks taste good. Is this normal or might there be a leak ?

Thank you in advance!
