Overlapping UV's in Infiltrator demo

Hi all,
When building the VIS_ArtDemo_City map from the Infiltrator demo I’m getting a lot (654 to be precise) overlapping UV errors and warnings.

Some values are 3.4% overlap … but there are also some assets that are at 50% overlap (like the male statue)

I was wondering - since this is an official package for us to learn from - if this is common practice to take overlapping UV errors and warnings for granted, as long as they don’t present a problem (artefacts and what not) in the final image ?

If not : is there a way to fix this within UE ?

I would also like to know the answer to this.
