I will just post screenshots to describe how sms filter is malfunctioning:

This first image shows two messages from my bank which were blocked by that wrong filter.

The second image shows the filter settings. Be sure that “all hidden numbers” or “all unknown numbers” were not included in this group members list, so the filter could only trash out these arbitrary 14 members. Anyway, even including them does not change a bit.

The third image shows that this sender (as a number 2265667589, corresponding to that “bankmoskvy”) was added to my address book, so the filter should not block him because he is a whitelisted trusted sender!
