you have duplicate form element names.
for the initial insert, you have an element named "name" date, and for the repeating form, you also use an element named "name", you need to use unique form element names.
on an insert, you wont use the manage relational table behavior, you only need the multiple insert behavior. so you should have the initial insert, then 2 multiple inserts.
before adding the multiple inserts, add a repeat region around the first group of repeating form elements and another repeat region around the second group of repeating form elements.
