How To See Suggestions For Word When A Red Line Appears On My Mac

Hi, I have made some illustration, this is the image when the revision show Final Showing Markup (marked with red ellipse) Vertical line beside text appears to mark the changes to the document So, I accept all changes, and I change the show revision to Final and the vertical line disappear. Thanks but I am having one problem with my Word on my Mac. It won't let me tell it to only use the UK English, it keeps using the US Spelling and as an Anaesthetist I don't want to be an Anesthetist! Is there a way to tell it that I am on the East side of the Pond and like it!
