How to write data back to a repeating section

Good day fellow Nintexers.  I need your brains to help me on this one.  I'm trying to figure out how to write data back to a repeating section for a much larger application, but have built a test case for simplification of learning.  Here is my scenario:

I have a repeating section bound to a Multi-line column.  In my repeating section I have 3 Single Line of Text boxes titled "First Name", "Last Name" and "Full Name".  I want to enter a first name (Obi Wan) and then a last name (Kenobi) and start with "Full Name" being blank.  The work flow already gets the XLM, divys up the data into two collections.  I can even build the collection called FullName that consist of the union of the two (Obi Wan Kenobi).  What I cannot seem to do is correctly write back this data to my repeating section. 

It works fine for one name, but if I have multiple it either applies the very last full name to each "Full Name" location on the list or plugs in the entire collection varible to each "Full Name" location. 

I cannot figure out how to write the data back to the specific index where it should be.  Below is the screenshots of my flow.  What else do you need?
