Locked out when using TranslatePress subdirectory feature

Hi. I have set custom login page in AIOWPS. I am also using the plugin TranslatePress. The problem arises if I use its option – to add subdirectory to the permalink. It ads slug like \en\ in the url and this also affects the login page and then I get 404 not found instead of login page when I enter WP. Can AIOWPS developers consider this and in the future updates add for example the second line of custom url, of find another way to fix this problem?! (I know I can use redirection but don’t want to, because it might be security risk)
Thanks.
