Thanks for the quick fix. 
I think it’s ok, the %{count} is nicely follow the English locale. Which also don’t use %{count} in some plural strings one form. Now the change is only we can edit the one form in admin too which is enough I think in this case. I think if it’s work correctly no need to other changes. I’ll update soon to test it. 
Seems everything works excellent That was a great pastime to change all these but I almost done with it. 
Thanks again and thank you @Moin too to point this out.
