At 22:12 there are two signs at the border. One states "WELCOME TO THE REPUBLIC OF RWANDA" and the other states "Rubavu District". It is very unlikely that the border between French-speaking Democratic Republic of the Congo (République Démocratique du Congo) and French-speaking Rwanda (République de Rwanda) would be labeled in English. The signs would more likely state "Bienvenus à Rwanda" and "District Rubavu".
At 43:25 in French speaking Rwanda the sign "VOLCANOES NATIONAL PARK" should be "PARC NATIONAL DES VOLCANS".
