How to edit "Add Insurance"

[r0seberry]

Hi, all.

I'm using Prestashop1.6 and I have problems.

 

First...

How can I edit "Add Insurance"?

I don't use other modules for shipping and I use paypal for payment.

 

Before people pay there is a box to check insurance. 

I want to it disappeared. Even I check it, price never changed. It should charge but does'n work.

 

 

Second...

As you can see the image

I have that words like (The fastes, The best price) and I can't find it.

Do you know where it is?

I want to take if off as well.

But there is nowhere. It's very strange because it automatically translated to other languages by system, but the words doesn't make sense.

 

I have to find it.

Please help me!!!
