Trouble with the Common App

Applying to College
1

Hello I am currently a senior and high school and working on the common app. I am putting in my teacher recommendations but I am having a bit of trouble. When I go to assign my teacher to colleges that require teacher recommendations there is an assign button and it works fine. However, when I go to schools like William and Mary (which does not recquire teacher recommendations but still accepts them) there is no button to assign and it is blank. How can I send to these schools??? Any help would be appreciated thanks.
