Just to clarify further, unless you have really bad hearing as to require your gain prescription to really amp up your Soft gains so you can hear soft sounds better, the Soft gains shouldn’t be amplified so much as to make you hear the floor noise, though. These are digital HAs after all, they usually have excellent SNR in the first place when it comes to floor noise.
You’re really the first Oticon More or OPN/S poster on this forum that complains about hearing the floor noise from the Soft gains. So something is amiss in your settings that causes this. Or something is wrong with the HAs, but it’s more likely the earlier and not the later.
