(You can try our option Hide/Show for URL match: http://prntscr.com/jofo6r – simply put in this field required language code from your url and save settings. This way you hide specific popup for some language and show it for all other, or vice versa – show it only for specified language and hide for all other.)
Sorry for the long response.
If I’ve correctly understood what you mean, you can’t hide additional languages neither with “Hide/Show for languages”, nor with URL match.
Please contact us through our internal support.
We will help you to solve the issue.
