It seems that Opera is still detecting your location as the Netherlands despite not using its VPN. Here's a shorter summary of steps you can take to resolve the issue:

Steps to Fix the Location Issue in Opera Mobile:
Clear Location Data:

In Opera, go to Settings > Privacy and Security > Clear browsing data. Choose Cached images and files and Cookies, and clear them.
Check Location Permissions:

Go to Android Settings > Apps > Opera > Permissions. Ensure Location is enabled for Precise location.
Disable Opera VPN (if active):

Even if you're not using Opera's VPN, make sure it is fully disabled. Check Opera's VPN settings to confirm it's turned off.
Enable GPS on Your Device:

Ensure that Location Services are enabled on your device for precise location. You can find this in Android Settings > Location.
Update Opera:

Ensure that you have the latest version of Opera installed, as older versions might have location detection bugs.
Clear App Data (if the issue persists):

Go to Android Settings > Apps > Opera > Storage > Clear Data. This will reset Opera's app settings without affecting your passwords.
Reinstall Opera:

If nothing works, consider reinstalling Opera to reset its settings completely.
