Invalid embed type: link with 2 vimeo videos

I have two vimeo video links out of 14 videos that aren’t working. I am getting the error invalid embed type: link. I don’t think it’s an issue vimeo privacy settings… as they should all be the same.

The issue links are Ronald Marshall and Professor Andrea Armstrong on this page: End Plantation Prisons - Videos

I believe other users have had this issue. I have not been able to resolve it.

I found a workaround by using this link format for a vimeo video - Professor Andrea Armstrong from Sara Gozalo on Vimeo

Absolutely welcome insight into this issue though.
