I cannot tell from the screenshot what's happening there. I visited the page and there are no clues in the markup, I would need access to be able to take a look in the back-end if that's okay?
I will mark your next reply as private so that I can get log-in credentials from you—you may want to create a temporary admin user for me to use that you can later delete. And be sure to have a current backup of your site, even though I don't intend to make any changes.
You won't necessarily see any changes you make until you flush your cache.
For some reason you have two Template Layouts with the same name (Template for Companies) but different slugs.
One (id 1354) is assigned to the Company post type and would be used to display all company posts.
Except the second (id 1353) is *individually* assigned to each of the company posts and is the one therefore being used to render the posts. (My advice would be delete this one and just use a normal template that is automatically used for all posts of that type.)
You can see that in the first of the screenshots.
You should also be able to see in the second screenshot that the Layout id 1353 (the one actually being used) still contained a stray closing square bracket.
I have deleted that and you should find (after clearing your cache) that it no longer appears.
