Problem with button without text and to wide div on mobile

Hello,

I found few  problems while setting up Boost Sell plugin.I`ve recorded two clips showing the problem “live”, you can download the files from wetransfer : https://we.tl/t-HTGYjMHHVa 

First problem is the  gray button without text after popup is shown (gray button without text.mp4)
It happens on mobile and desktop as well

Second problem is a div with price being to wide for mobile, client needs to scroll sideways to see the summary price (div to wide for mobile.mp4)
