Panadaptter gain on 20M different from other bands

My SmartSDR panadapter on for my 6500 on 20M recently changed after the RTTY contest this past weekend so now the increments are 0, -20, -40, -60, -80, -100 and -120 and the noise floor is no longer visible. The other bands are 0, -40, -80 and -120 and the noise floor is visible. The scale up/scale down arrows do not correct this problem but they do effect the visible gain of the signal as expected; however, the noise floor is never visible. The RF gain is at 0. Changing modes has no effect. A while ago I had this same issue on 15M and a reboot of the PC and radio restored the correct settings. Unfortunately it doesn't work this time. Ideas???
Thanks.

You can adjust that by sliding over the numbers up or down I believe.

Thanks, but I have tried that. Yes, the numbers change but are never the same as on the other bands and the noise floor is never visible.

John just to be sure you understood Gary. Have you left clicked and HOLD on the scale which at that point you can move it up and down.

Wow! For the longest time I could not see the noise floor on 160m. Using the arrows didn't solve it. I just tried the suggestion of left mouse button and dragging and it worked!

Thanks for that suggestion! Problem solved here...
