Can't logout in pre-domain mode

Hello,
I have a problem with loging out from page.
In my wordpress installation I use pre-domain mode(with option hide unchecked) to switch beetween lanuages. I have a probelm with links(https://www.ads-software.com/support/topic/link-to-other-language-inside-page?replies=4) and I think that it’s a part of the problem here.
Now the problem: When I login on my customer account, not mater in which language(pl or en) i can’t logout, clicking button logout, getting redirected to same page but still logged in.
I think that problem lies in cookies stored for language domain, aand when loging out trying to delete from wp address.
