Hi, dropdowns only display one or two options, it's very difficult to use them. I found this bug when adding languages to a group, tested on firefox and chrome latest version.
A screencast to see this behavior : https://wp-translations.pro/site/wp-content/uploads/2018/05/Screencast_24-05-2018_12:13:42.webm
autocomplete__results seems to have a bad value in margins or position
I will make this top priority
