I agree, it looks like the column date ranges were changed after Adobe created the calculation... so the dates there would reflect the original definitions.
You can, however, open up the Percent Change calculated metric, then open the Target and Compare Date ranges and change the definitions to properly roll with proper MTD ranges.
@DipikaSomvanshi "Last Year MTD" is not a standard date range in Adobe, someone in your organization created that as a preset... if it is not coming back with the correct set of data, then you or that person will have to fix it.
Here is how I would create a "Last Year MTD" range:

If I don't want to include today:
The only difference being whether I use "End of" or "Start of" in my End definition.
