5.0 Pro update issue?

I updated MaxButton Pro to V5.0 this evening and was shown the error:

Fatal error: Call to undefined function vc_add_shortcode_param() in /home/content/p3pnexwpnas10_data03/05/2501505/html/wp-content/plugins/maxbuttons-pro/assets/integrations/visual_composer/vc.php on line 23

I rolled back to last version I had activated (Version 4.14) however this triggered a different error.

I’ve now activated the free version of 5.0 which seems to be working but has removed some of my button features (2nd line of text, custom font).

Please could you advise if there is an issue with v5.0?
