SUMMARY

The GUI element to save current rendering settings as a preset adds/changes
parameters to the profile.

STEPS TO REPRODUCE
1. Open the Render dialog.
2. Click on the MP4-H264/AAC preset
3. Check full color range rendering and set quality to 65%
4. Click on Save current settings as a custom preset.
5. Set the preset name to eg. Test ; do not change anything else.

OBSERVED RESULT

The actual parameters for the MP4-H264/AAC preset are : 
ab=160k acodec=aac channels=2 color_range=pc crf=26 f=mp4 g=15
movflags=+faststart preset=veryfast real_time=-4 threads=4 vcodec=libx264

The actual parameters for the custom Test preset are :
ab=160k acodec=aac bf=0 channels=2 color_range=pc crf=18 f=mp4 g=15
movflags=+faststart preset=veryfast real_time=-4 threads=4 vbufsize=0
vcodec=libx264 vmaxrate=0k

EXPECTED RESULT

Both should be exactly the same.
