Adding a video to page of featured works

I would like to upload a 22-minute video to one of my gallery pages, Short Films. I do not have any other videos uploaded to my site, yet when I try to select the file, Squarespace tells me that I only have six of the allotted 30 minutes of video storage remaining. I tried to upload this same video about three times unsuccessfully, so I wonder if the system is confused about how much storage space I've actually used. I have not been able to figure this issue out, nor can I find the proper wording to locate a similar thread on this forum. Please advise. Thank you!

You may want to check this for limits:

If you're not above any of those limits, and you definitely don't have any other videos uploaded, then I would recommend contacting Squarespace support, they should be able to help you.
