How do I remove the "Have a nice day" remark from my statement email text? there does not seem to be anywhere to change the statement template

Hello Regor99, 

Welcome to the Community page, 

So the way to changed this is if you go to the main cog wheel top right hand side> click on account and settings> sales>scroll down to messages section>click drop down arrow under sales form and select statement and remove what you want from the message> then click on save and done.
