Calendar showing all 24 hours of day when work settings are set between 8 hours

[MegaMiaow]

Hi, I've always had calendar set to display working hours only but today the view has changes to 24 hours with a lot of redundant spaces. How can I revert to the previous view? Thanks.

Figured it out. It was set to Hourly )(60 min) intervals which zooms the view out. Setting it to 30 mins have returned it to the previous view.
