add users to groups based off file name.

Currently what im doing is I'm importing a list that contains groups names. I then take that list and i want to import the list that matches the group name and add the members in that list in to the groups. Below is what i have so far, however it seems to be adding users to say both the groups

$Domain1 = 'domain.com'

$groups = import-csv .\GlobalExport_$Domain1.csv

foreach($group in $groups) {
$GroupName = ".\"+$Group.samAccountName
Import-csv.\$groupName.csv | foreach {add-qadgroupmember $group.samAccountName -member $_.DN}}

what it does it takes the users from the list and adds them but adds the users from one list to both groups

attached are some files that im using
GlobalExport-domain.com.csv
testgroup26.csv
testgroup102.csv
