Shop Manager role missing

Hi,
I run a small woocommerce online shop and I want to give all shipping to someone to do this for me.
So I installed AAM to control the access of the shop manager to lock him out of all the business parts of woocommerce. I want to show him only the page for new orders, print shipping label and invoices and allow him to check off the orders as processed.
But after selecting checkboxes at “capability” and “save” shop manager was missing!
Also under “user” the role of shop manager wasn’t to find.
After deactivating AAM the role was back.
Does anyone the same experience?
