Tab Widget Don’t Show Shortcodes

Hello,

I am trying to add a tab widget to the right side bar. When editing the tab contents there is automatically added . I thought this was the problem so tried another approach. I added Layout Editor and put the tab widget in it but the result was the same – it is not the actual widget displayed but the shortcode itself as text. When I add a simple Text widget everything is OK.

Is there a limitation in using the tab widget? Is there a way I can fix this issue and make the tab contents visible?

Thank you,
Vasil Krastev
