Minimalism cart/checkout different from the Demo

Hello team,

I proceeded to purchase your theme and install minimalism but this is different from the demo I saw before purchasing.

I am attaching images of cards and checkout on a desctop and on a mobile phone so that you can see that it is completely different from the demo.

In addition to the different view, I also notice some delay in loading mine in relation to that of the demo.
I don’t know if this has to do with an additional css code that may have been added for this change in the image.

Thanks in advance
