JSON syntax highlighting not working for strings with greater than 1000 characters?

Hi, folks -- I'm using Splunk 6.0.1. I'm trying to ingest JSON and have the JSON syntax highlighting automatically parse my input. After experimenting, it seems that I can only get the syntax highlighting to work for JSON lines with less than 1000 characters (998 works). How can I fix this? I've tried setting TRUNCATE=0 in the app's props.conf file. I've tried resetting the maxvaluesize=10000 within the limits.conf file. Both, yield no luck. Thanks!
