In tor browser, try going to https://www.ip-tracker.org/. This will verify weather tor is hiding your location or not. If the site does show your real location in tor browser than yes your tor is not working correctly. However if it shows an unknown location the tor is working correctly.
The issue you are describing does not sound tor related; what's most likely happening is this website is ONLY accepting ip addresses from their approved country list, or they are resolving the ip address and dter
