Missing Titles on Blog Posts

Hello
I’m having trouble finding a fix for missing blog post titles.

User lever: I am fairly proficient with WP and becoming more so on Visual Composer but do not know much about appending code without help. I can do it, but need specific instructions.

Site: https://www.ministrybuilders.com
WP Version 4.7.3
Environment: IE11 and Chrome Version 57.0.2987.110 (64-bit). Problem is evident on both browsers.
Using Visual Composer CSS 5.1 to build site pages.
Using WP to post ordinary blog postings.
I have static HP and send my posts to my blog page.

Issue: Blog reposts correctly with every update on my blog page ( https://www.ministrybuilders.com/blog ) but does so without titles on any of the posts.

I have done a little troubleshooting. When I disable Visual Composer, page titles reappear but the rest of the site’s content is lost without the plug activated. However, when Visual Composer plugin is activated, then my blog post titles disappear.
I assume there is something in the code or visual composer that is causing my blog posts to remove or display page titles = none. I have looked at Visual Composer for a setting and cannot find anything that would cause it not to display the titles of blog posts.

Any ideas on how to solve?

Thanks in advance for your assistance.
