Hello, dear woodpeck...
 the thing is that there are several reasons for this.. one of the reasons is the wrong name in Russian, and you are right that I should have noted this in the comments... 
another reason is that our state language is Azerbaijani, and this very strict rule applies to everything without exception.. in addition, we have the Latin alphabet, and even semi-literate Russian tourists will have no trouble understanding the names of settlements... 
another reason is that the OSM overview map of the world contains the names of only large cities and regional centers of Azerbaijan - and these names are written in several languages ​​of the world - English, French, German, Russian and others.. small settlements are not displayed in the overview map, so there is no need to write them, for example, in Russian...

in any case, I thank you for your letter, and I think next time I will try to take your comments into account..

with respect..
