Base: changing a reports sorting order

Have moved an OpenOffice base project over to LibreOffice, why, because I’ve been unable to create a new report there. (Project presently has 3 reports.)

I have a copied report on my list of reports. I wish to change the sorting order. Searched online and watched a video.

Solution seems to be to open the report in edit mode, go to the view menu and click on the sort and grouping menu (video is from 2014 - www.youtube.com/watch?v=wkpOrvMrXyQ)

Problem is, this menu option does not seem to be listed in my view menu. Do I need to download some type of add-on, has this menu been moved in version 5.0.0.5?

Very confused and need assistance.

Many thanks
