After upgrade to Patch 14, ALM 11.00 does not show actual defect graphs by Release in Management Module, Quality tab.
Both upper and lower graphs only show one line marked "Unknown". No other priority option is shown, although I select all of them in the filter. There are several defects linked to the test sets of this particular Cycle. No actual defects shown even if I uncheck "Only target cycle" checkbox in the graph filter window.

The functionality used to work well before the upgrade (I am not sure what patch of ALM 11 was installed before this last upgrade).
All other functionalities are currently working as expected.

Cannot figure out what may be the cause of not displaying defect's statistics in the Quality graphs of the Management module.
Please advise.
