Hi Sue ... Welcome to WikiTree!
I'm sorry you're starting out with a badventure, but at least it's only a very small one and you did the best possible thing by asking about it here - any time you have questions, G2G is the place to go - there are lots and lots of members who are always ready to answer questions here, so you'll never have to wait very long, and with so many members, there are bound to be some who will be able to answer any question, no matter what the topic!
In this case, I looked at Rhonda's profile and don't see anything wrong, but that's only because I'm used to seeing imported GEDCOM's. The original GEDCOM often contains all that marriage/children information for a person's parents in the biography section. The information appears to be correct, although it is not information about Rhonda - only about her parents and siblings. When you look in the data section (above the biography), it shows Rhonda's parents and siblings as matching the information in the biography.
You can delete that section in the biography for Rhonda and her siblings, but you might want to leave it in the parents' biographies since it is about them.
Profiles were not added for Rhonda's spouse and children - they were probably not included in the original GEDCOM. You can add them whenever you'd like to by clicking the link to "add spouse" or "add child" that you'll see on the editing page.
