Lumen light leak vs mesh scaling

Hi all, I’ve been learning UE5 intending to use with on archviz projects while doing some testing, noticed some light leaking trough walls, even after following lumen documentation to get optimal lighting (separate walls, 10cm+ thickness etc).
One solution I found that eliminated this issue was scaling the mesh (both mesh and distance field resolution - in this case done it at import, from blender to UE).
Can this cause any issuer later on, considering that my idea is to scale everything at the same proportion?
