The problem was that I had the old tag in place. I just had to make these amendments, that I have found here, after careful reading the fifth(! - concentrated too much on other details) time: https://sourceforge.net/p/ijbswa/support-requests/1667/

* Replace previous s@Tagged: Proxomitron FrontProxy@$0@i (cf. user.filter) by new one: s@^.*Tagged:.*ProxHTTPSProxyMII.*FrontProxy.*@$0@i

*Replace previous TAG:.*?Proxomitron (cf. user.action) by new one: TAG:.*?ProxHTTPSProxyMII
