Error Getting Current Volume Growth

When I login in the Compellent Enterprise Manager Client 2014 R2 Build 14.2.10.53 and select one of the Storage Centers that are present on our environment, I got an error (shown in the image):

"Error Running Method

Error Getting Current Volume Growth [Storage Center: 22311]:"

This occurs while accessing the two Storages we have: 22311 and 22313. This issue is something new and didn't appear a few months ago, maybe before the last update (not sure).

The system is working normally, but this error appears every time I open the GUI.

Could you help me?
