Fantastic! When I first created the child theme I used the child theme configurator, however it didn’t create an rtl.css file which I need for my site, so I used One click child theme ,an old plugin, to do the job. It did create an rtl.css but made the above problem. Used the configurator and your code and created rtl.css myself and now I’m able to use the custom template.
Thank you very much @lebcit
