I have created a new HOOK_theme_suggestions_node_alter and added a new $suggestion to load a custom twig file. Now in the debug under inspector I can see that the suggestion of new file is already there. Now I created that file but it doesn’t seem to be being loaded.
Now the location of the module is under modules/custom/gf_them_module/ and my custom theme is location in themes/custom/gf_theme/. Now the new file which is node--products-template--simple.html.twig is located in themes/custom/gf_theme/templates/contentsame location as the other suggestion twig file like thenode.html.twig`. Now upon clearing the cache it doesn’t load the file. Not sure what is the problem can anyone please help
Above is the location of the file. I placed one under system and the other under content but it’s still the same 
Here as you can see the file is being suggested but it’s not being loaded
