Assert Step Not Executing All Assertions

I added an Assert step into my test script and within this assert step I've created four individual assertions on various fields. When the assert step is executed, only one of those individual assertions is executed. The others indicate "UNKNOWN" in the message column.

I've unchecked both of the following settings in Project Preferences and Test Case Options:

• "Discards successful test step results to save memory"
• "Abort test if an error occurs"

Is there a project setting that I'm missing that needs to be set to ensure all asserts configured into an Assert step are executed?
