The items are in the inventory before the armor was added, they were there.
ok bro!!
let's go from the beginning !!
The error that I see is in the name of your xml file, you named it 9500-9600, but you can't end it that way, the correct way the name must be 9500-9599.
try with that, after this we will see the lines, tables and values that you created within this file.
I just tried to create an xml file of items, where I have hat, coin, weapon and armor, it worked perfectly !! just respect the rule of the file name ending in 99
