Bro, I see the secreenshoot you just need to download it on "Link Download".

Then, import the data JSON File to the website i gave to you for check the history bet. I already see the image and your history bet on there all of them, they store the total bet on the date you are doing a betting. JSON File contain all of your bet on that's date, one of the example on your screenshot you have 1250 Bets and Date 6/30/2020. Download the JSON File on "Link Download, and that's mean the JSON File contains 1250 Information of your Bet History has been made on 6/30/2020.

I see on there, and there is no problem at all. You should know the work of their mechanism store of betting history.
