Hello sir_Paq,
That sounds like you are referring to the Seller Business Information that eBay adds near the bottom of listings. If there is a difficulty with this data showing, you will need to contact eBay support as that data comes from your eBay account directly and is not submit by Auctiva.
I did check a few of your listings using the eBay mobile app and I was able to see this data there - I found it in the area about the seller by tapping on Show More and then tapping on Seller Legal Information; so that information does show in the eBay mobile app.
If you find issues with this displaying correctly on your device in a mobile browser, please feel free to reach out to eBay and let them know so they can have a look into it.
