Block validation failed

As Tom pointed out, without the actual code of the block (specifically the save function) it is impossible to tell you exactly what the issue is. That said, if you compare what was generated by the save function and what was in the post body, you’ll see that there is content missing in each of the <p> tags in the area of <div class="chacha-row">...</div>. You can start by looking at how that content is generate/saved in the save function.
