full english map ?

[pulsarinformatique]

Hello
I have a french (native) / english / german 5.2.5 joomla site with 5.0.2 phoca maps.
I use OpenStreetMaps

In the Phoca Maps Configuration settings I can select :
OpenStreetMap
OpenStreetMap (French)
OpenStreetMap (German)

even if I select OpenStreetMap , the names on the map are displayed in their local languages, not in english

but if I select OpenStreetMap (french) or OpenStreetMap (German) , the names on the map are correctly displayed in french or german!

So why can't we just have map in full english please?

thanks

cyril
