Display subtitle in mx module

Hi,

I believe you are referring to the excerpts displayed on modules. Please note that not all modules display an excerpt. That could only be achieved by modifying the module files.
If you are referring to the post subtitle, that will be displayed in the post page only, not on modules.
There are similar topics with solutions that could be tried for adding excerpts to modules that do not normally have them, or subtitles, like these ones
