Couldn't change intensity of Datasmith AreaLight

I’m using Unreal Engine 4.22.3, windows 10 build.
My artist colleague exported 3dsmax objects to ue4 using datasmith.
So, today i tried to play with lights and change their intensity. So i create simple blueprint that finds all actors with DatasmithArealight component and then get access to that component. After that i use SetIntensity function to set the intensity from max_value to 0. I run simulation mode and see that there is no effect. But when i looked at the light properties (via world outlier), i noticed, that actual value was set to 0, but visually there is no effect. Additionally, when i tried to change value manually (from editor) the light’s intensity changed.
How does actually work? How to change intensity of DatasmithAreaLight actor?

Best regards, Alex.

Can somebody suggest a solution?
