Noticed a small, but perhaps easily fixable bug while experimenting on some designs:

When copying long handed inserter presets onto a fast (perhaps others as well) inserter while the fast inserter is still in ghost form before being placed by bots, it changes the drop/pick locations to match those of the long handed inserter, similar to those possible with bob's adjustable inserters, effectively creating a long handed fast inserter.

Mods present are only the dependancies of the Krastorio 2 spaced out mod. Elevated Rails, Quality, Space Age, Change Inserter Drop Lane, flib, Krastorio 2 Assets+Spaced Out and PlanetsLib. Would assume "Change Inserter Drop Lane" is the culprit

Looks janky as hell but might be a niche feature as well

Can you test if the problem persists in vanilla K2 , if it does report it to raiguard , otherwise i will need to import the fix from k2 source code.

This is a problem with the "Change Inserter Drop Lane" mod and not your SA port it seems, there seems to be at least 1 bug reports already present and Raiguard seems to be aware of the issue but is likely not on the priority list for fixes
