'Meters: Reset' Doesn't reset CPU and Disk Cache meters?

Could have sworn in 10.5 and prior, that this key command also reset the CPU and Disk Cache peak lights, but maybe I’m remembering wrong?

Yes you are, it is only for Audio Meters & unfortunately there is no alternative Key Command to clear the others - you have to click on them to clear.

FYI, it is not a CPU indicator, it is for VST performance of which CPU is one component along with several others.
