look on the right side of the window for upper filters
right click on upper filters
left click delete
windows will then ask you to confirm deletion
click yes
look on the right side of the window for lower filters
if you do not see lower filters, you may be out of luck on this one.
right click on lower filters
left click on delete
windows will then ask to confirm deletion
click yes
Close all the windows that are open
restart the computer
