Rookie mistake: I set radpot and sphpot in settings.ini but Multiwfn kept using defaults. Turns out iautointgrid= 1 was silently overriding them. Switched it to 0, problem solved.

It's a Windows version. I've set Multiwfnpath but it doesn's seem to work.

Multwifn doesn't seem to read the contents of settings.ini properly. I have modified a relevant part of the settings.ini:

radpot= 150
sphpot= 974

restarted the Multiwfn, went to PDI analysis just to get:

Allocating memory...
Radial points:   45    Angular points:  170   Total:      7650 per center
...
To improve accuracy, please try one or some of following treatments:
(1) Enlarge "radpot" and "sphpot" in settings.ini
(2) Set "radcut" in settings.ini to 0
(3) Choose option -6 to change to much more expensive molecular grid
(4) If diffuse functions were heavily employed, remove them.

Does anyone know how to fix this?
