Maybe you have the "Devices" tab open(?), but the "templates" are in the POU pool. You can open it from the menu: View - POUs, or if it is already open, select the POUs tab which is normally next to the Devices tab. All objects which are part of a library are in the POU pool, because they should be device independent (at least most of them).
Have you tried running it in the soft plc (Control Win)?
On your device, change the setting in CODESYSControl_User.cfg: [CmpUserMgr] SECURITY.UserMgmt.PasswordPolicy=DISABLED
