Conflicting definitions between the radiotap HE PPDU format field and 802.11axD2

Hi folks,

It seems that 802.11ax D2 defines, in Table 28-18, in HE-SIG-A, a
1-bit format fields (B0) that takes the values 0 for HE TB PPDUs and 1
for HE SU PPDUs and that is reserved for others but must be set to 1.

However, what seems to be the equivalent radiotap he ppdu format field
is 2 bits and uses different values.

Have I misunderstood? What is the resolution of this?
