We are in the process of doing a bulk export of 37 cabinets, some of them have a grain matched front like in the image below.

When we come to export this into Optinest, the grain matching is doing something but isnt right. All of the parts are flipped, it should be sortable in V carve but something isnt right.

We are using 7.07k for Polyboard and 2.31t for Optinest. I have tried it on a few different cabinets and they are all having a similar issue so it isnt something in the cabinet. Could someone look into it please.
