Hi @elena92
Looking at your screenshots, it seems you’ve done everything right. But since they’re not in English, could you please confirm that you’ve followed our guide available here: https://woocommerce.com/document/setting-up-taxes-in-woocommerce/#price-display-suffix
If yes, then you can run a conflict test to help you identify the cause of the issue.
- Temporarily switch your theme to Storefront or Twenty Twenty-Four
- Disable all plugins except for WooCommerce
- Repeat the action that is causing the problem
If you’re not seeing the same problem after completing the conflict test, then you know the problem was with the plugins and/or theme you deactivated. To figure out which plugin is causing the problem, reactivate your other plugins one by one, testing after each, until you find the one causing conflict. You can find a more detailed explanation on how to do a conflict test here.
I hope that helps! Let me know once you have done a conflict test!
