jetpack sharing not works with Ulimate Auction plugin

Is this the plugin you’re using on your site?

Could you post links to auctions where the buttons should appear, so I can have a look?

Yes, above is my auction plugin. I am using free version. still my site beginner level.
my auction url is : https://buylanka.lk/auctions/
I like is is better so add share buttons bottom of the description. Thanks for support.

Thanks for the extra details.

Jetpack’s sharing buttons were built to added at the bottom of the post content, whenever post content is displayed using the_content().
The auction plugin doesn’t seem to output the post content anywhere in its auction shortcode. Instead, it outputs its own data, related to the auction. As a result, Jetpack’s sharing buttons won’t be displayed anywhere.

However, it looks like the auction plugin author added some filters to his plugin. These filters would allow you to hook the sharing buttons in different locations inside an auction box.
I’m not familiar enough with the auction plugin to know which filter to use to hook data after the bid description, but the auction plugin author could help you there. Could you start a new thread in their support forums, and ask them what filter to use to hook data right after the auction description inside each auction box, when using the auction shortcode?

Do not hesitate to point them to this thread if they need more info.

Once you have that information, we’ll be able to hook the sharing buttons using a method similar to the one described here:
