Blog page can't handle shortcode

When using shortcodes at the first couple of lines of a blog post, this shortcake is shown on the blog page, instead of being executed.
This is effect is seen here: http://www.persawa.be/euro-2016-frankrijk/euro-2016-blogpagina/

To avoid this, I also wrote a post excerpt where no extra shortcode is used, but it doesn’t seem to be possible to show the excerpt on the blog page. Only the first few lines of the actual post can be shown.
