802.11ad Decoding Error

I have the following snapshot for a capture for 802.11ad DMG Access Point generated by ns3 simulator:

While going through the fields of the DMG Beacon, the wire-shark interprets part of the information in a wrong way. For example in the fixed parameter Sector Sweep field (3 Bytes), I pass the following information in the DMG Beacon during my simulation:

1. Sector Sweep Direction = 0 (Beamforming Initiator)
2. Sector Sweep CDOWN = 8
3. Sector Sweep Sector ID = 1
4. Sector Sweep DMG Antenna ID = 1
5. Sector Sweep RXSS Length = 0

As a result, the encoding of this information according to the standard as illustrated in the following figure should be as following:

Byte (0) Byte (1) Byte (2)

00010000 00000100 00000001

In more details:

1. Sector Sweep Direction = 0 (Beamforming Initiator)
2. Sector Sweep CDOWN = 00 0001 000
3. Sector Sweep Sector ID = 0000 01
4. Sector Sweep DMG Antenna ID = 01
5. Sector Sweep RXSS Length = 0000 00

Note: The left most bit is the most significant bit.

So as you can see the wireshark dissector interprets them i the opposite way.
