loosing contacts for groups in widows live mail windows 8

This is the same question asked last year on windows 7 I am using windows 8 had to get a new computer. never had this problem with win 7 machine.  Windows Live Mail Groups, my contacts are listed properly. But when I write an email and select a Group to send to, most of the Contacts are not there.

I have removed the Group and re-installed the Group with the contacts several times and after a couple of days or hours they disappear again. I ran registry fix using the Norton tool but does not always fix the problem.  Any Ideas
