Customizing invoice

Hi,

I have a bilingual site (French and English), and I managed to pretty much customize the invoice language dependent, even the logo changes according to language preferences.

However, there are few things which I did not manage to adjust:

1) Invoice title format:
This fields consists of the fixed word "Invoice" and the dynamically created invoice number. I tried several "tricks", but I could not figure out how to change the word "invoice" AND have the invoice number dynamically created.
As a workaround, put "Facture/ Invoice # [INVOICENUMBER]", but I'd prefer to show either Facture or Invoice, not both.
Can this be done?

2) Plan description ("Item")
Plan description is always showing in English, no matter the language selection. (Note: When a user is signing up for membership, then the plan shows properly in English or French).
How could I show the plan description in the selected language?

Thanks for any advice.

I believe that's the "Invoice title format" parameter within CBSubs > Settings > Display > Invoices. You should be able to provide a language string or define then translate it, but I'm not entirely sure language translations work there. Example as follows.

It shows as the correct language during registration, but not when logged in? Please clarify further as it should always display in the language of the viewing user. If there is no viewing user then it's always displayed in the language of the site.
