Sorry about that, and thanks to your reply.
I was following Erika`s response and followting that, it seemed to work for e.m.
"Export a Json with nonessential data checked, then downgrade Spine and reimport it.
Make sure that in the project you are exporting there aren't any features that the older Spine didn't have, such as audio, because it will fail to import in this case."
Hence the images of my export setup.
