Can't export to Shutterstock in ProRes format

I'm trying to export video for use on Shutterstock. I have done so using H.264 with no problem but when I try ProRes it will not work on SS.  When uploaded and I select view a larger preview, I get a message: "No video with supported format and MIME type found" and it will not play.  SS support is telling me to turn of HDR - which I did not think was on, since I have not checked the box shown below - yet it seems like it picks one of the three options anyway.  I don't know if this is really the issue at all, maybe support is mistaken.

Below are the settings showing in the export screen.
