Is the tx bitrate field what you are wondering about (vs the measured speed) ?

This is a known bug caused by the QCA WiFi driver firmware blob. The exported
TX bitrate value is utterly bogus. Only QCA is in the position to fix that.

There have been attempts such as this one:

Not sure this fix addresses your case. Sven might know.

Cheers,
Marek
