I am struggling with Filters in GM5.7, I have set up a filter to find all records in a defined town and this works fine, I then set a seperate filter to find contacts with a defined title or reference, this does not find any records although the expression is build from existing fields i.e title contains design engineer, I have checked that such records exist. I also have my own keys within the mail merge fields i.e DE and the filter does not pick this up either.
