Mailchimp Templates breaks when edit design

I have licenced “Sentinel - Responsive Email + StampReady Builder” and downloaded and imported the sentinel mailchip into mailchimp.

i did “edit design” and “save & close” then “save exit”. when i reenter “edit design” the template looks not good anymore. many blocks are suddenly lost. why?

thanks for help.
