An abnormally large population. Bug

[Barbaris 111]

I recently returned to aoh2 with the addon+ 1.4 final mod. Playing in the Kaiserreich scenario for Russia, I discovered a strange anomaly on the map. The population in the territories of present-day Iran was abnormally large (about 25 million people per province). There was also another province in Iran, but with almost 100 million people. And in the area near Tibet there was a province with almost 20 million people. All the evidence is presented in the screenshots. I've never come across this before. Has anyone already encountered this?
