Weekly and Monthly Data Access

I have AB 6.20.1. When I click on the weekly (W) or monthly(M) in the icon bar, it does not switch to weekly or monthly data. It stays as daily. What am I doing wrong? Many thanks!

Many thanks Tomasz. I had done a forum search but must have used the wrong keywords. I appreciate you pointing me in the right direction. Thanks!
