Those logs can't all be for one IPS protection, as the severity and confidence rankings are different on different lines.
I assume you have checked for any rule-based or global exceptions. Also look in the matching TP profile under IPS...Additional Activation and check what is configured there, although normally this would Inactivate a protection and not set it to Detect.
Beyond that I'll need to see the full log card for a Prevent and another one for Detect on the same IPS signature, and your TP policy containing the rule matching this traffic. You can PM it to me if you wish.
