Membership 3.4.4.1 where shortcodes goes?

I've a site with Membership Pro 3.4.4.1 and I'm trying to use [level-somelevel][/level-somelevel] shortcode but my the content is rendering the shortcode as text and is not hiding the content as should be, any advice? How do I use shortcodes on that version?

PS: I'm on WP 4.1.1 and I'm using plugin Types so the post where I'm trying to use Membership Pro is a CPT
