Hello,
You might have a bug or conflict with your current theme / plugins.
Can you please visit TranslatePress -> Settings -> Advanced
Then, enable these features 1 by 1 in this order and try to see if it makes a difference. Also please disable or clear the cache if you have any.
1. Fix missing dynamic content
2. Disable dynamic translation
3. Fix spaces between HTML attributes
4. Fix broken HTML
I can also suggest a conflict test:
??*Briefly* disable all other plugins and enable the default Twenty Nineteen theme. If this fixes the problem, as it probably will, enable everything one by one, checking each time to see when the problem returns.
Please let us know when you find the conflict so that we can take a look and see what we can do about it.
Best regards,
