Splunk 6.5. Issue with Sort and Fields like commands

Hello Team, We have dashboards with queries containing commands like sort - and fields - , what we found after upgrading 6.5. what we found is the dashboard is automatically updating queries and removing spaces. This in result causing us no data found for the queries. We compared the same dashboard queries in 6.4.2. The automatic trimming happening in 6.5 only. Any help much appreciated. Seems problem with "-" symbol only THanks Praveen
