Separated perimeters

Hello,

I have been having an issue where the prusa slice (on left) is printing the perimeter separated and leading to weaker structure. I'm not sure what the issue is, but what occurred to me was the problem was from the PLA somehow... Furthermore, I have tried to raise the external perimeter on advanced options but seems to not solve the issue.

On the right that's a slice from another software, one that I do not have access to anymore, there is no space between the walls...

Can I force the settings to output extrude more so that it adheres to the sides? The perimeters are separated, I can fit stuff between them in the vertical axis they are like 90% separated. I'm assuming that wasn't supposed to be, am I wrong?

Any suggestions are apreciated, the holders are just an example, i have printed and tried other stuff, they all end up the same...

The printer is a modded ender 3 v1 with direct drive, original creality (upgraded 2 months ago) noozle 0.4mm, the PLA is a generic brand (i know, im planning to buy decent one next time, i have little expirience, started to be more into printing recently).

I found the solution, I'll leave it here for future reference.

Turns out that the filament options has a setting "Extrusion Multiplier", increasing it from 1 to 1.35 solved the problem, now the walls are looking adequate and the overall structure is solid as it should be.
