Multiple mapped domains stopped working after recent updates

I have three mapped domains for one site (see attachment).

This configuration worked perfectly before the last update. Now http://www.rsd-treue.de and http://www.lesen-reisen.de are not redirected to the primary domain but to the WordPress folder of the site which is http://www.rd-lpp.com/treuevorteile-de/.

Can you please help me with this?

Thank you,
Bogdan
