Can't remove Service Window

I tried to figure out what the rep was saying to get separate service windows different days of the week so I added a service window for Weekend Evening and for Weekday Evening (one was edited the original name of Evening). It didn't work so I deleted one and renamed the other back to Evening. But now when trying the client booking demo there are both Weekday Evening and Evening service windows for the 5-8pm slot. It is only showing one on my Service Window availability settings for Evening!. Please fix this.
