Plugin incompatible with plugin HTTPS

I have secured my admin panel through the plugin HTTPS, that means all traffic is routed through a SSL proxy of my web hoster and all requests of the type
http://example.net/wp-admin/…
will be transformed to
https://ssl.webpack.de/example.net/wp-admin/…

When I try to save any changes in the Antispam Bee plugin, the save button always points to
https://ssl.webpack.de/wp-admin/…
and completely misses the proxied domain of the page.
