Notification Template does not save correctly

Notification Template does not save correctly

Hi,
 
Whenever I configure the text and the layout for the various notification and reply templates the layout does not always stick so when an email is then sent they layout is incorrect.
 
I can amend many times and still the layout will either revert to what it was before the change or only some of the changes will be saved.
 
Many thanks,
 
Matt
