Then, since all the options of the module are fine, all I can think of is that there is some cache on your website which prevent you from seeing the new "version" of the module and that the caching system is displaying you an old version of the module.
I would recommend you to:
Disable the cache in Joomla configuration.
Site -> global configuration -> system -> "Cache settings".
Disable, if it's enabled, a joomla cache plugin.
Check your template' options for a potential cache option and deactivate it.
