"Add to Custom List" Panel

Hello,

On a dramas page when you click the button to add that show to a Custom List (to the right of the "+Add to List" button under the poster), the panel displaying our Custom Lists opens to the left. This was fine on the old website layout, but since you flipped the layout this panel now gets clipped by the edge of the browser.
It's worse when you have your browser set to a larger zoom (larger text). It does the same thing on a mobile browser as well, almost to the extent of not being able to read the title for any of our Custom Lists.

Could this be corrected to drop open to the right instead?

Thanks for the help!
