Manually add Sender to account not an option

I am unable to manually add a sender to the account using the instructions found here: https://community.onespan.com/documentation/onespan-sign/guides/connector-guides/user/managing-senders

I tried to follow the directions to add the user, but the options are different from in the instructions.

I am assuming the setting for “ Sender Account Method” is not set to Manual.  This is my best guess, and I could be completely wrong.

Please advise
