Hi ashley roehl. Videos should not disappear from your collection unless you specifically remove them. I would love to get some more information from you on the specifics of what is happening. At a quick glance, I see that you have 3 collections: the first one has 4 videos, the 2nd one has 7, and the 3rd one has 4. Are you expecting there to be more in each collection?

It's probably best to email us at support@grokker.com. Please let me know the name of your collection and the video that is missing. I'd be happy to see what I can find out.
