Datasmith messing up textures with Sampler type as normal maps

Hi, we have a problem when importing projects from 3dsmax and corona render, Some of the materials come as a normal map in the diffuse slot, the problem is that when we check the texture, the texture that is placed on the diffuse is the correct diffuse, but its messesd up, we need to find again the original texture and replace all the nodes with this one, and we have A LOT of nodes in the fabric shaders, so here are a bunch of screenshots…
Any one with a solution for it?
