P Throughput not displayed in NV2 mode

Under /wireless tables/registration , in NV2 mode , P throughput is not displayed ,however , in A(802.11) it is. Why is there no displayed parameter in this mode? RB435G.ver. 5.18

same problem 433ah 5.20 and omnitik and sxt, Although not a major problem’m used to measure the quality of link with

P Throughput

too bad , sure makes things easier to deal with at a glance…
any chance of correcting this Mikrotik?
