[Elecraft] K3S CW AGC-F Not Working?

All: I noticed that he AGC-F setting on my K3S seems to have no effect when in CW mode yet it works in SSB mode. When switching between AGC-F and AGC-S the decay is slow so it appears to be "stuck" in the AGC-S setting when in CW mode. The AGC settings are: AGC DCY = SOFT AGC HLD = 0 AGC PL
