you can delete the styles in the plugin styles.css and put them in your mail stylesheet, this will work too if you want it to behave globally.
wordpress is listing the custom shortcode styles AFTER the main stylesheet, therefore the second stylesheet will take precedence in this conflict.
if you don’t want to delete the stylesheet just test it out by putting it in comment quotations /* */ .
let me know if you have any other issues (this works for me)
