Unable to open RT file generated by Slicer

Support
1

I loaded two nrrd volumes, one has the CT volume , the other has a binary segmentation mask. I am able to load and view them without any problem.
But when I try to save it by exporting to RTseries, it generates the dicom files for each slice and a single RTS dicom file. But when I try to load this directory it tries to load each slice as individual files along with the RTS like in the below screenshot

When I hit OK it loads all the slices as individual slices (is there any way it can be loaded as a single volume ?) but it gives a big error when it tries to load the rts file

Some images may be loaded using “Add data” window, but in generatl you need to open DICOM files using DICOM module.

I would recommend to use the latest Slicer Preview Release, as it has many DICOM support improvements.
