What useful purpose do these Radio Settings accomplish?

Since the SDRC Server remembers the last users settings, I found this one this AM on my Super Station #4:

Image is a bit grainy, but...
ATT 24dB
PreAmp ON
Visual Gain 25

Can the user (or anyone) explain why one would run 24dB of attenuation while runing the Pre Amp and adding 25 dB of Visual Gain? 🤦‍♂️
I'm just trying to see the logic here. 🤷‍♂️

Just thinking out loud...
