Import csv wrong displayed

[stratomagic]

 

good morning
I have a big problem

I have to import a script into a csv file, I put it under the "short description"
the problem is that imports all but when I go to the product page, the whole page is badly distributed, attach photos

the most strange thing is that if I go into the bo, and go into the source code the code is correct, if I click on save (without touching any code, leaving it as it was imported), the page you see properly

I am importing a script code to display a video player (jwplayer)

how can I do?

 

thanks in advance
