Using the 'Select all' check box to the left of the 'Display Name' column header on the member list impacts the display of the member list filters. Steps to repeat:
If you check the 'Select all' checkbox and then clear it before clicking the Filter icon, all the filter options are removed.
In each case after using the 'Select All' checkbox, clicking the Filter icon 3 times (to display, remove and re-display it) will show the correct filters that have been applied.
This bug can be repeated on the mobile site and app.
