Analytics - Old Stages that have been deleted are still showing up

When I run my report in analytics, it shows two stages in separate categories due to the stage name being changed in the CRM. How do I get it to combine them like they've been updated in the CRM.

"No Show - Tour" is the new name and "No Show - Tour or Open House" was the old name.

It's making my dashboards and analytics reports look sloppy and we're having to manually add the numbers together to get the correct numbers.
