Just received this replacement filter.  Same model number Ive always ordered but, there is something wrong with it.

The filter will not properly engage with the socket in the refrigerator to allow it to swing up and into place for proper installation. It appears as if, the protrusions on the filter head are not large enough to engage the locking/unlocking mechanism in the refrigerator.

Addendum: Just saw other reviews describing same issue. Filter inlet/outlet piece too long to fully seat and seal in refrigerator.
Need a replacement ASAP.
