Promobox buggy if in column

Hi
next issue:
The Button is of course supposed to be IN the box – not below.

Here is the code:

[av_one_third first min_height='' vertical_alignment='' space='' custom_margin='' margin='0px' link='' linktarget='' link_hover='' padding='0px' border='' border_color='' radius='0px' background='bg_color' background_color='' background_gradient_color1='' background_gradient_color2='' background_gradient_direction='vertical' src='' background_position='top left' background_repeat='no-repeat' animation='' mobile_breaking='' mobile_display='' av_uid='av-ooag']

Hier kommt der Text hin - also der zu marcus, oder Alix oder was auch immer du willst. Du musst nur darauf achten das die texte einigermaßen gleich lang sind damit sie unten einigermaßen bündig abschliessen.
