Weird Error but everything looks okay

I get this error but the models and segmentations I imported look really good… Is there something wrong?

SetConversionParameter: Conversion parameter ‘Default slice thickness’ not found in converter rules!

anyone? Please help?

What does this error even mean

This just means that the segmentation was created with an earlier Slicer version or the Default slice thickness parameter is missing for some other reason.

The parameter may be needed for planar contour to closed surface conversion if contours are not defined for every slice.

Most likely you can ignore this warning.
