Problem with the map of Serbia

OSM maps of Serbia are written in both Serbian alphabets, Cyrillic and Latin. Users from Serbia thought that the folders had an error because they were on both letters. This is the map of Serbia from Navikey.
White_54 posted a map with names in Serbian Cyrillic. It looks great, but when searching for addresses, it's the same as Navikey.
7ways does not find many cities and streets on both maps with the system Cyrillic and Latin keyboard.

Example: Ratkovo village/Đure Jakšića street

The images from the Magic Earth Navigation & Maps application prove that the problem is not in the OSM map of Serbia, but in the 7 ways application.

Request
Navigation 7 ways is the best navigation with OSM maps. There is nothing better. I am asking the developers to fix this problem. I'll help whatever it takes.

1.
I ask the developers to add the option from the picture. That the map of Serbia be in the Serbian Latin script.
And if possible option 2 (In Local Language) in Cyrillic.

2.
Please find the error why there are no names of streets and cities in 7 ways, but they are on the OSM map.
