Can you attach a sample test plan ?
Or at least show your configuration:
- of HTTP Request 
- Thread Group
- HTTP Cookie Manager
- HTTP Header Manager

2/ Also please provide jmeter.log after activating debug mode:

in bin/log4j2.xml uncomment lines 75 / 76:
    <Logger name="org.apache.http" level="debug" />
    <Logger name="org.apache.jmeter.protocol.http" level="debug" />

Start jmeter and run the "buggy" request once .

3/ If you can also put fiddler capture.

4/ Also please provide some context on application

With current status 

Thank you
