Magic UV not working as expected

Hi everyone

For the past few weeks I’ve been messing around with Magic UV and real world UV scales. Everything was working great until 2 or 3 days ago. It seems that applying the scale density to the “loop” mesh doesn’t work as expected, well, the scaling is off.

In the image below you can see the X Dimension is 108mm.

After using a 50x50mm mesh and texture to get the scale density, I applied it to the “loop” mesh and as can be seen below, the scaling is off when measured in Photoshop, 129.5mm

.

I am using Blender v2.82a because I have an AMD card and this is the best version for me at the moment and Magic UV v6.2.0.

I have attached my blend file so you guys can have a look and maybe tell me what I’m missing?

Any help would be greatly appreciated.
