Hi,
If you go to Settings/TranslatePress/Advanced/Miscellaneous Options, you have to check “Translate numbers and numerals: yes”.
If this still doesn´t work, you could try my solution for a similar problem. I needed to change a telephone number in my translation to danish and swedish, because we have different contact people for different languages. I guess that, because the telephone number was inside a top bar preceeded by a telephone icon, TranslatePress has not recognized it as text to translate so there was no “pencil” to click on. I simply couldn´t select the number. What I did was to insert “Tel.:” before the number so that TP could detect some text (Tel.:) and show me the “pencil” to translate. Maybe you could find a similar way to trigger the translation option in your case.
I’ve enabled the Translate numbers and numerals option and it helped.
Thank you so much for your support.
