the_title echos both title and subtitle

[pmpr]

Describe the bug
After plugin activation, I use the_title() and I mean title, but the plugin forces me to have both title & subtitle together. I can use the_subtitle() for that purpose. I think this is not good to change default behaviour of the_title(). by the way, how can I have separate the_title() & the_subtitle(), as I have some exact theming needs?

I know that I can disable it like explained here, but I think it should not be the default behaviour out of the box.

To Reproduce
Steps to reproduce the behavior:

1. Go to your theme and put the_title() somewhere inside loop.
2. Load front single page or post or event custom post.
3. Scroll down to title section
4. See that you are forced to have subtitle & title stick together and you have no choice to only show the title.

Expected behavior
One should be able to have title and subtitle separate from each other so that (s)he can better use this plugin in her/his theming procedure.
