I respect all of my customers and try to support in all cases. During purchase you have agreed to our Terms and Conditions where it is clearly written what is covered by the support. After that also i write code most of the time for customers. But that has some limitation.
As you are overriding templates in your child theme, you can easily add h2 tags in those templates. Eg. in directory.php add
<h2>Member Directory</h2> just after ?> in line 16
