Pay with like plugin: Short codes wont work

I use short codes from my theme (UDesign) or plugins to have buttons or download links for documents that do not work with the pay with like plugin. Example:
[pwal id="64214832" description="test"]

[custom_button text="Custom Button" title="Custom Button" url="http://www.your-link-goes-here.com/" size="medium" bg_color="#FF5C00" text_color="#FFFFFF" align="left" target="_blank"]

[/pwal]

The short code in the middle is a button short code from my theme. After the page is liked, the page reloads to show what should be a button to be clicked on for a link, but instead shows the short code.

I really need help fixing this issue.
