Hi Stefan
Specifically, the destination related to ESR is SAP_PROXY_ESR as shown below.
From your screenshots, it does look like the wizard is able to connect to the ESR content, so it is quite weird that the activate interface is not there. As such the only other things I can think of to check are:-
- check that the target host is configured to the correct PI system
- check and refresh cache on PI system
