I am trying to setup a repository for MRI DICOM and 3D Mesh files. I am using some pictures from a camping trip as dummy files. I've added a few Properties (all single line text <10 characters) to test out the repository and to represent metadata later on. In the toolbar and grid settings I've checked those properties to be sortable. When working in the file repository I can not sort by the custom properties. When I try and sort by the property is just sorts by the file name instead.

My goal is to make a system where a user can sort and filter these files and download the results in bulk. I'll worry about more advanced features later.
