Gallery is displayed twice

Hello
When I enter the shortcode in the post editor, the gallery appears twice.
Once in the post as desired, and once over the menu.
What is the problem here?
I use the template FLEX
Does anyone have a solution?
greeting

Hi
I think that the problem is that you have something that automatically takes the article content to put it in the meta description
this is a bad method , you must put a custom written meta description in your page
CEd

For example, if I have the shortcode of simple gallery, I do not have the effect
The effect only occurs with the shortcode of Mediabox

that is right because you can use Mediabox CK anywhere in your page, not only in the content
the tag replacement is using a different method

have you tried to set a text in your meta description ?

When I enter the code in the Helix Blog Options it works.
Only then is the title under the gallery
The title should be above the gallery

please send me the url of the page to check that
