Total EBS period over period description comparing incorrect dates

[gmg105]

In CUDOS dashboard V5.3, the Storage & Backup page has a descriptive box named "Total EBS Period over period".

It always compares the previous month compared to the current month leading to incorrect cost decreases as the periods aren't comparable.

In my opinion, it should compare the previous month with 2 months ago, so that one could get an understanding of the trend month over month. That's closer to the Amazon S3 tab behavior, where the total spend is compared to the previous (month) period, so that we'd get a descriptive trend.
