Imported schema is not creating any data in new project

[HelsKRW]

Hi, I'm using the new method of importing schemas for the first time (now under manage schemas). I've imported the JSON schema that I've previously applied to multiple sets of data - but it doesn't seem to be creating any data in the current OpenRefine project. This is what I see - so I've selected the schema I've imported, I've tried with or without saving it as new - but the schema doesn't appear below as it used to do when I imported one using the previous import schema method.

Has anyone had success with this or is able to see what I'm missing! I'm struggling to find the relevant documentation.
Thanks

Helen

Thanks to @Yorvick for some off line help with this
The issue is now resolved. I'd not understood that schemas I'd downloaded prior to these OR's changes to managing schema would no longer work and would need to be recreated.
Thanks
