Field Extraction Rule Only Works if Receipt Time Checked

Hello, 

I have created a FER for my proxy but for some reason it is not working right. 

If I click the "Use Receipt Time" checkbox then I can see all my fields from the rule. If I do not click that box then none of the fields display. I have verified that the timestamp in the logs is correct and I have had the rule in place long enough it shouldn't matter. 

What am I missing that this is only working with that box  checked?
