Basket and checkout page

I have Threadwears theme on my site and all worked fine, then somehow checkout page was comlpety diferent than I had, and my payment solotion doesnt work there, as it is block based now. I can't find what is the issue, I did roll back to latest back up and all was ok, then next day again the wrong checkout page comes up. I cant even find fields in site redactor to create it like it was. I had it same as threadwears demo page have, just translated and in pages design. Can someone know why is that? my page: www.apogjers.lv
