Hi Fajas ,
Thanks for reaching out to us and sorry for the late reply! We were on a break last week.
It seems like the cause of this issue is a conflict between TranslatePress and our setting, "Make all labels have same width".
You can perhaps add this custom CSS to your site:
width: 100% !important;
This should make your buttons have the same width. We will perhaps improve our setting so that it can be compatible with TranslatePress in the future. 😃
Please let me know if this works for you!
