Believe it or not, this is something that happens to a lot of people. What's happened here is that the All Products was added as a list item and now all the products are becoming children of that parent, creating a staggered list. Two ways you can attempt to correct this:
Create a top level called "All Products Temp" (cannot be the same name as one of the list items). Move all the products underneath the "All Products Temp". Then delete the "All Products" list item. Rename your top level as "All Products"
Delete the list and start over. This time start by creating the top level "All Products" Then reload the product list using "All Products" as parent, or leave it blank and Anaplan will automatically assume All Products is the Parent.
I apologize. I read it the wrong way. You did state it correctly the first time. The issue was within the P2 Products list. After reloading that list, it was a success! Thank you very much for assisting me. I greatly appreciate it.
