Principal is right. However, if you look you will see that the icon for ArrayOfUAasItem is still showing as a list i.e. sheaf of paper. Hence, your inner look is not configured correctly. Your loop paths are wrong
1st loop - either /results/Results or /results/Results/UAs. (Not sure where the first array is in your structure)
2nd loop - /results/Results/UAs/ArrayOfUAsItem
Looking at the screenshot it appears that your path is still wrong.
The loop starts with ‘genericDocument…’. However, you are mapping from ‘results/Results/UAs/ArrayOfUAsItem’
Best thing to do is right click on the list that you want to loop over and then copy it. Paste the result into the input array property of your loop. Make sure you only map after doing this. Any transitions that you made before configuring the loop will be invalid and you will have to remove them and remap
