In a WiFi capture log, why the 11ac “beamformed” bit is shown as both “true” and “false” in wireshark version 2.4.2 (v2.4.2-0-gb6c63ae086)?

I don't have many adapters that pass up BeamFormer information, but for the ones that do I see consistency in the capture. Perhaps you could share a packet that has the information that you find inconsistent? So it is a 'bit', it should only have one of two states, so not sure how it could be true and false? That being said, I only have captures where it is always false so cannot positively show in all cases where it is correct.

Also the capture adapter you used would be useful.

Thanks, Bob. I have a capture showing "True" in the first red rectangular box, and "False" in the second red rectangular box. But this web site does not allow me to upload any picture/file since "points is < 80" (which I don't know what that is about)?

Please file a bug on this on the Wireshark Bugzilla, and attach the capture to the bug. (The capture file will be a lot more useful in determining what's happening than a screenshot would be.)

That's issue #14266, which is now fixed.
