Missing FR translations in invoices

When I set my test sites to French, those strings are translated: https://share.cleanshot.com/nKbyQRN2

How are you configuring your site to be in French? It should be in Settings > General > Language

You can also see that these strings are translated in the translation site as well: https://www.sunshinephotocart.com/glotpress/projects/sunshine-photo-cart/fr/default/?filters%5Bstatus%5D=either&filters%5Boriginal_id%5D=442&filters%5Btranslation_id%5D=7096

You are right, the translations are working correctly.

The site has always been set in French at Settings > General > Language BUT my own admin account is set in English and this is causing this salad of languages when viewing invoices. But my client is using the site in French and I can view the invoices correctly and fully translated when using her account.

Sorry for this non existing issue alert.
