Some of the posts on that home page are displaying the full content, not an excerpt. Examine your homepage template’s PHP. For excerpts you replace
the_content( ....may be stuff in between the parentheses... )
with
the_excerpt()
Yes I have the_excerpt but some are still displaying the_content but as seen not all are?
Looking at View Source on your theme, your home page is pretty complex code. I can’t see the PHP code when I look at the View Source but I can pretty much assure you the theme itself is doing something that is causing this behavior.
Each of your home page news articles are wrapped in a div
<div class="entry-excerpt">
This is not typical WordPress theme coding. It suggests that either PHP or Javascript are manipulating what is appearing. Does your theme have a control panel that has an option for whether home page posts are displayed as either full content or excerpts? That option could override the code you are changing in some way.
I opted for removing the excerpt. Seems to be an issue with how some articles are formatted, however I could be wrong. Looks better now without them anyway. Thanks for your advice and attention.
