Worse ironing in MK4S than in MK4

Hello,
After upgrading to the MK4S and printing the same parts, there's a noticeable difference in ironing quality. On the MK4S, it looks different across various parts of the bed. In most areas, the quality is very poor. It seems like the ironing in the MK4S is not adjusted to the height of the bed because in some spots, it barely touches the print, while in others, it's actually scraping filament off the print. I tried changing the ironing option, for example, from 15% to 10% or 5%, but the issue isn't that the entire bed is bad — it's that the ironing quality differs in each part of the bed.
Here’s a comparison of the ironing quality between MK4 and MK4S.

RE:
I've also noticed issues with the MK4S ironing being worse than my MK4 too with the same exact settings, that's what led me here, however I can say when I was having ironing issues on my MK4 it was because layers weren't level.
I increased the infill from 15% > 25%,
disabled combine layers every X layers,
set infill to adaptive cubic,
and set the ironing flow from 10/15% > 30%,
...those settings have been a night and day difference on my MK4's ironing quality.
