Thanks for reporting. This is a regression in Slicer-4.11.20209030 that was fixed in [https://github.com/Slicer/Slicer/commit/9aa9ed8b8aa06704ece1f0caa50d46cd7825ea4a](https://github.com/Slicer/Slicer/commit/9aa9ed8b8aa06704ece1f0caa50d46cd7825ea4a).

Unfortunately, Slicer Preview Release is not functional yet ([No images shown in slice viewers in latest preview release (Slicer-4.13.0)](https://discourse.slicer.org/t/no-images-shown-in-slice-viewers-in-latest-preview-release-slicer-4-13-0/13899/4)).
