Many thanks for the help. It work! Although I didn’t understood how it really works.
Sorry by asking and is there anywhere documented how it exactly works? because at Output Formats docs I couldn’t find anything regarding how to name the template files (like the filename name must have be list.[kind].[suffix])
I will submit the issue regarding the lower-cased template filename.
Anyway, thanks for your help. I will study more how hugo works and maybe I will figure it out.
