Hi Jerzy,
The system is working as intended. The movement type 322 - Transfer from Unrestricted to Quality is designed to do the same way irrespective of the inspection type or the parameter defined in the inspection type. This is the standard behavior of the system.
In some scenarios, the inspection type 08 is used for Goods Receipt against the stock transfer orders. So, the "Post to inspection stock" option is available in inspection type '08'.
Hope, This can clear your queries.
