Shortcode not working – gets posted as plain text

Hi TagDiv

I would like to add a shortcode before and after post content in the single post template.

I’ve tried on a Blank Single Template – by adding the opening shortcodes in a Column Text-element above the post content. And the closing shortcode in another Column Text-element after the post content – like this:

[tdc_zone type=”tdc_content”][vc_row][vc_column][vc_column_text][paywall-content][/vc_column_text][tdb_title][tdb_single_subtitle][/vc_column][/vc_row][vc_row][vc_column][tdb_single_content][/vc_column][/vc_row][vc_row][vc_column][vc_column_text][/paywall-content][/vc_column_text][/vc_column][/vc_row][/tdc_zone]

However, the shortcode after the post content doesn’t work – it only get’s posted as plain text. Is there a way to make this work?

Thanks in advance.
