Easyblog 5.0.19 broke my buttons

I have added buttons to the bottom of several of my posts in previous blog posts. When upgrading to EB 5.0.19 the buttons that were still working with 5.0.18 are no longer appearing properly.

You can see a recent post made using JCE editor after installing 5.0.18. The hyperlink button at the bottom of the post was working fine until upgrading to .19.

After installing 5.0.19, I created the following post. The button is also not displaying properly. This is when I discovered the issue.

The issue appears to be the same for both posts. Here is the code I am using:

<div><span style="font-size: 12pt;"><strong>If you want some help learning weapons retention and disarming and other essentials of self defense, consider joining our Tactical Arts Academy Self Defense Program.</strong> Not only can we can help you in class with the training mentioned above, but we can also help you stay safe with other training. Click the button below to learn more.<br /></span></div>
<div> </div>
<div> </div>
<div><span style="font-family: Arial; font-size: 12pt;"></span></div>
<p><span style="font-size: 12pt;"><a href="programs/self-defense" class="readon">Learn More about our Self Defense Program</a></span></p>
<div> </div>

What do I need to do to get them working again? This is an important part of my marketing.

thank you,
