path to custom template

hi, when i want to customize your template it doesnt work
i looked in your codes and in /includes/helpers/helpers.php line 252 and 263
you write : ZVC_PLUGIN_SLUG . “{$slug}-{$name}.php”, wihout “slash”
to work for me i have to add the / in your code like this
ZVC_PLUGIN_SLUG . “/{$slug}-{$name}.php”,
best regards
