IWRL6432: [IWR6432] Definition of 16 values in gestureFeatures

Tool/software:

Dear supports,

According to reference, there are 14 parameters in Gesture Features TLV.
Refer to link: https://dev.ti.com/tirex/explore/node?node=A__AM.ODmyj-wSKpxFI.SPOug__radar_toolbox__1AslXXD__LATEST

However, gestureFeatures has 16 values. Is there any reference to point out these value?
