Invoice Template, Renaming of Terms do not show in Subscription invoice, but do in Books

Invoice Template, Renaming of Terms do not show in Subscription invoice, but do in Books

- I have changed the Name of the standard payment term "Net 0" to " A réception" (French invoices).
- I have used the Invoice template "Standard European" 
- In the invoice, for Terms, it show up "Due on Receipt" on invoices generated in ZSubscription,
HOWEVER when creating invoice for same customer in ZBooks, for Terms, it show up " A réception" (which is what I want and expect)

Any reason why the invoice are generated differently if generated from ZSubscriptions vs ZBooks?
