1. The location of the lake did not change.
2. Ukrainian was only added to the existing list of translations of the name of the lake into other languages ​​of the world. No changes were made to the spelling in other languages.
3. The link to the Ukrainian Wikipedia is a source for confirming the correctness of such spelling in Ukrainian, and was not established as the main source of information about the lake.

Ok, I will make the corrections, thanks for the comments.

Tak, zgadzam się.

Oops, my bad.
