[Plugin: Mesa Shortcode] Theme Bentuestu – Lightroom Image-Shortcode doesn't work

I create a new posting for a image with the mesa shortcode plugin > Lightbox image.

No matter whether I choose the width of the image -for example- 50 or 500 and post the shortcode in my BLOG, the automatically generated 2 Dividers above/under the picture have always the same distance. Thats why the postings doesn’t have the right distance to the previous one.

TEST a) 2 images with first width 50 and second width 500

50 width

500 width

TEST b) image normal posting without mesa-shortcode – normal posting from wordpress (but unfortunately not responsive)
