Anchor id not working

Hi
I can not solve why the ID anchor is not working on this page
When I click on the buttons … it is not working
https://toup.cz/vice-vrstve-kominy-fasadni-kominy/

Here is how the ID set, it is correct?

But it is working when using address from other pages.
E.g. when I paste to browser it works >

Hey Dan,

This is most likely due to incompatibility between the latest version of Cornerstone and old version of X. Please always ensure that everything is up to date according to our version compatibility list at https://theme.co/docs/version-compatibility. Please follow the best practices when updating your theme and plugins. See https://theme.co/docs/how-to-update for more details.

If that doesn’t help, please do the following troubleshooting procedures related to the issue.

  1. TESTING FOR THEME RELATED ISSUE
  2. TESTING FOR PLUGIN CONFLICT
  3. CSS/JS CUSTOMIZATION

ONLY if none of that helps, please give us the following info in a Secure Note.

  • WordPress Login URL
  • Admin level username and password

You can find the Secure Note button at the bottom of your posts.

Hope that helps.
