Anchor links within a page always open in a new window

Hi,

I have created a long page with anchor links in it:

a 3 column part with my newsletter form in on of the columns:

<a>Newsletter</a>

and on the bottom of the page in a color section (Avia Layout Builder) an anchor link, so that the user, clicking on this link, will get to this part of the page, where the form is:

... meinen <a href="#newsletterabo">Newsletter</a> abonnieren ...

The anchor itself works fine – however, when clicking on this link, then it opens a new browser tab with my site in it – although I’ve tried to fix it with a target=”_self” … it doesn’t help.

I’ve created a test page without using the Avia Layout Builder – but here it’s the same: anchor links are opening in new browser tab.

Any idea?

Thanks.
