[مغلق] How to translate text inside custom field

Background of the issue:
In raypa.com, I forgot to add [wpml-string] to some texts inside a custom field that only appear on mobile. Now the pages have been translated and I have 2 texts that don't appear in string translation. I cannot add now the [wpml-string] shortcode to the default language and then update the translations with ATE editor because I would lose all the changes I had to do to each translation - to part that did not appear in ATE like shortcodes. The 2 texts are "tempeartura" and "presión" and appear for instance here: الرابط المخفي (on mobile view only, see screenshot).

I have tried using the "autoregister string for translations" and the "track where strings appear on the site" options but the strings did not appear...

Symptoms:
The texts "tempeartura" and "presión" do not appear in string translation.

Questions:
Is there a way to make these 2 texts appear in the String Translations?
