Cross tab report not displaying latest data

Hello All,

I have a cross tab report as sen below:

Name                         2014           2015

                                    Dec             Jan          Feb          Mar          Apr          May

Payable                     123              12              45          67             89           10

Receivable                1                    2               3              4               5             6

Accounting                 1                   5               8               5               2            2

However, when i refresh the data it does not return any results for June, July, Aug, Sep and latest months.

Is there any way I can modify this cross tab to return the data from the recent months as well?

Thanks!
