CW Pot Not Working?

[K8ND]

New installation of a recently-purchased used RRC-1258 MKII box. Cloned the configuration from the remote terminal I've been using for several years. Everything seems to work, but the CW Pot does not change the CW speed. Paddle is plugged into the RRC1258 box, and CW is sent well, but only at a fixed speed.

CW speed seems to be fixed at whatever speed is entered in the 'Speed pot min wpm (5-99)' field of the 'Keyer Setup'. 'Speed pot max' is set to 40 wpm.

If I start N1MM+, it initially correctly shows the speed currently configured as the minimum wpm (and being sent by paddle), but it does not affect the actual speed of the keyer when adjusted up or down.

From the 'Info' panel:
HW   8
Software   2.95
Bootloader   1.10
Compiler   4.6.2

Thanks!

Good to have confirmation that the pot is 10k linear.

I posted a photo of the apparently-failed pot in another post, and have added it here as well.
