ZBrush 2019 scale problem

I'm having an inexplicable problem with a model scale. In 'Size' tab it accuses 2, as it should. In 'Export' tab it's on 905, multiplying the two of them = 1810 which I figure is in milimeters right? In 'Scale Master' function it accuses 1.81 cm, exactly the height I want. But by exporting with 'Fbx Exporter'  in Maya I'm obtaining a 1810 cm height model and in Blender a 18.10 cm with an object scale of 0.01 in the correspondent axis, which results in 1810 cm when you turn the scale to 1. My final goal is 1.81 cm.
Is this a known issue? I need that scale right because of .exr displacement map exportation. Should I reinstall ZBrush? (I've done that a couple months back already). 
Thx!
