Clock wipe effects CANNOT be dragged into the timeline

Hi All, 

    I am new to Premiere Pro and currently using the newest version. I am trying to create an animated circle into my clip but for some reason, i cannot drag the "Clock wipe" effect into my timeline. When i drag it, nothing worked.  I tried several different things, and it seems like all the effects under "Wipe" don't work, but some effects are fine. Please help! Thank you
