Sharing not showing on coupons generated from plugin

Hello.

I use this plugin – https://www.ads-software.com/plugins/affiliate-coupons/ to show coupons on my site. However, for some reason sharing buttons are not shown.

Coupons are checked in Shariff’s plugin settings page, I even tried to check the box “Add buttons after this content.” for particular coupon but nothing works.

On the other side, if I add [shariff] shortcode to coupon description it is not parsed to show the buttons (instead I see [shariff] on the frontend).

Do you have any clue what might be the reason and how to fix it?

Thanks in advance.
