Filter not working

Hi I am new here. I am trying to implement ERPNext. When I create new customer , Customer group and territory filter not working as expected. When I select “All customer groups” no records are filtered but when I clear everything records start showing.
Similarily for Territory. Whats the use of parent group it doesn’t show child

For tree structures, frappe uses a different filter, namely descendant/parent of. Equals is a strict equal to filter.

If you want all the territories/groups falling under the parent:

  1. Click on Add Filter
  2. Select the field
  3. Select Condition: in this case descedant
  4. Select the parent value.
