What should I do if disabled activity types still appear in the calendar page?

The Calendar page by default shows a legend of the calendar types, with colors. If you've disabled some calendar types and don't want them to appear on the calendar, use Page Composer to hide them.

Here are the steps:

1. Navigate to Sales > Activities > My Calendar.
2. Create and enter a sandbox with Page Composer enabled: Click your user name in the global header and select Edit Pages.
3. Click the Select tab.
4. Scroll to the end of the calendar where the legend is.
5. Click Edit Component.
6. In the Component Properties window, deselect the Show Component checkbox.
