Sorting Classes On Dashboard
The dashboard has the ability to sort your view of the upcoming and past classes. You can sort by:Date/Time
Class #
Course
Client (Certain package)
Location
Instructor
Enrolled
The sorting option is located next to each option, signified by a red arrow. If the option is not selected, it will show up as a grey up and down arrow.

Make sure to check if any of these options has been accidentally selected, as it can rearrange your dashboard without you noticing.
