TablePress Plugin Buttones are not working with GP

Hi,
Tablepress plugin buttons are not working with the Generate Press theme.

I have added tablepress plugin with a button for one post for Amazon India Coupons but buttons are not showing and looking like this : https://imgur.com/a/HWbsmns

With other themes, buttons are working fine and looking like this : https://imgur.com/a/z4Mtgnw

I am using following code on tablepress for button

<a href="URL" target="_blank" rel="nofollow noopener noreferrer" class="wpsm-button green medium">Button text</a>

Please let me know what changes I have to made.

Thanks
