CMS drop down not showing all options in the collection to select from

I’m having trouble finding two custom video fields I added to my collection. The videos I want to add to the site have been uploaded to the collection like so,

however when I click the drop down menu to add the videos to the collection they are not shown in my collection list and don’t know where to find them. I only have access to “Social Video 1-4”
