SignalTap autotriggers constantly without meeting conditions

Is there a reason SignalTap offloads acquisitions immediately after "Run Analysis" is requested, even when trigger conditions are not met? I tried removing and adding the *.SDC timing commands to me...

I have experienced two similar situations:

1- The JTAG cable/programmer is faulty. In this situation, unexpected behavior is observed. Try testing another cable/programmer.

2- The signal clock domain is different from the SignalTap clock. In this situation the condition may trigger, but you observe that it should not.
