Email with Knowledge articles templates are send blank

when working with the knowledge articles under the KB records

we fills in the necessary information within the body of the email,

but when the email is send,the email reverts back to its original form and all the information entered is gone.

We realise, that if the focus is out of the body when the email kb record is loaded it doesn'T work.

But if we hit refresh or F5, the focus is in the body and the information entered will stay their after the emails has been send.

Any idea why?
