It looks like you have a coordinate system issue. please describe the steps you took and provide sample data so people can help you sort this out.

Most likely you have applied a warping transform on the volume. It is a [limitation](https://slicer.readthedocs.io/en/latest/user_guide/modules/volumerendering.html#limitations) of Volume Rendering module that non-linear transform must be hardened on the image to make it appear in correct position.

Can you take a screenshot of your Data module to see what volumes you have in your scene and if any transforms were automatically added?
