New filter leaking even though inserted properly

[penguin]

Hi, I just tried to install a new Pure H20 filter (PH21510) to replace my Maytag UKF7003. I've been getting filters here for years but this is the first replacement I have had that leaks/drips inside the refrigerator. Any suggestions on what else to check? The old filter works fine when installed, except obviously says "Change Filter". Thanks.
