Reprojection of SWEREF 99 in ArcGIS Unity distorts the latitude of the map

Question

Hi, I'm trying to use a basemap layer created with the SWEREF 99 TM coordinate system and when its loaded in to Unity the latitude seems to be distorted. So if I place something 1000 meters from the origin and then measure its distance from the origin to the object its registers as 1600 meters in Unity's units. I'm trying to get a map where Unity's units is a 1:1 for locations placed around Sweden. Is this something that is possible? The local map says its using 32662 WKID, can I change the projection to 3006 (SWEREF99 TM)?

This is solved, the problem was one of the layers I were using had a different coordinate system. So I changed that layer to use the same coordinate system as all the other layers (SWEREF 99) and now it projects the map accurately!
