Sorry, I have no chance to add a comment since I have too low reputation so far. But I would like to give a more exact answer to this question. Here is a very logical answer to your question, to complete the answer that @Steve gave you:
Your relay is using Tor version 0.4.3.6 which was released on 2020-07-09, which uses GeoIP2 database "Last updated based on December 3 2019 Maxmind GeoLite2 Country" (read from source). If we then go further to RIPE Database, we can see that last update to your IP range was made on 2020-04-15, which was after the date 2019-12-03 when your GeoIP2 database was released.
Solution:
Simply wait for Tor to update their GeoIP2 database.
PS. It is so easy to find people on Google by only using four keywords: Tor, Relay, Ukraine and Lark :-D
