Change of obfuscation.minimum.value property works but does not display properly

We changed the parameter edu.harvard.i2b2.crc.setfinderquery.obfuscation.minimum.value in the crc.properties file to 10. It works properly, i.e. when there are less than 10 patients found for a user with obfuscated access rights it does not return an obfuscated number, but only the info that there are not enough records found.

But what it displays is this:
patient_count: <3

instead of the expected result:
patient_count: <10
