Enfold - import layout bulider templates file not working

No errors, but templates not appearing. I’ve exported templates from one Enfold website and am trying to import them into another, and they are not appearing. I go to Enfold Child → Theme Options → Import/Export → Upload Layout Builder Templates File - the file is already uploaded so I select it and click on Insert Layout Builder Templates File. I get a message “Alright! All options saved. No problems whatsoever” but the templates aren’t there. Any ideas?
