missing sum Actual execution time

[wingking84]

i follow the steps in user manual.
when i click test project/test plan, i can see:
Estimated time for executing 492 test cases (hours):41.15
Time used for executing 492 test cases (hours):26.66 .

but when i click testsuite, i only see:
Estimated time for executing 492 test cases (hours):41.15

'Time used for executing 492 test cases (hours):26.66' is missing.
what should i do ?

only one testsuite in testproject.the exec time of testcase in this testsuite have been set.
when click testsuite,
within adding some "echo" in printDocument.php, i see the surface cause is that
exec time $min['totalMinutes'] value is alway 0.
when i set manually $min['totalMinutes'] =10 ,the report show :
Time used for executing 492 test cases (minutes):10.
