I think you might be doing this in the wrong place.
In the web interface if you go into your movies and do a long click on one of your movies you will see the display change and each movie poster will have a check box appear.
You can select multiple movies by clicking the box for each. When you have selected all the movies you want for a collection use the 3 Dot menu - "..." in the upper right corner to add to a collection.
Should be pretty self explanatory from there.
See attached example. Hope it helps you.Go to the full post
