I’m using Nirvana (again) on a website, I managed to translate nearly everything on it but I couldn’t find the Presentation Page column I created in string translation (WPML).
When adding column widgets to the columns areas, if you use Polylang (at least – I cannot test with WMPL) you have the option to display that column widget for all languages or a single language.
You can create separate widgets with the properly localized version, and set them one for each language.
