MO2 - Files in your Overwrite Mod - how to resolve

[veggiesoon]

So I'm setting up a new PC to run Skyrim SE after playing on PS4 and desiring more. I'm slowly adding in some basic mods following the usual guides when I noticed an error icon in MO2. Upon further investigation the error message says "there are files in your Overwrite Mod". I think the last mod I installed was the Achievement Mods Enabler and when I navigate to the folder there is a file in there linked to that mod.

Is this a major problem and if so, how and where should I move these files to in order to solve this issue?

Here's a link to a screenshot showing what's going on: https://imgur.com/a/v86VlFN

files which getting created while the an application is opened through MO will get stored in the overwrite folder. doesnt matter if its log files, preset files or simple mod merges.

logs dont do harm and can stay afaik in the overwrite folder

EDIT:
mod merges should moved out of it, at best with creating a new mod
generated files like reproccer or FNIS should also get synced to their appropriate mod / or created in the first place
