Hello,
First is if you are editing a column's properties in the edit columns dialog of the datagrid and you select or unselect the sortable or filterable options, the properties part of the dialog goes blank as if no column were selected.
Second issue occurred when trying to upload a gif of the issue above. Tried many times, and even though my gif files were below 30kb, the upload would error out stating that the file size was above the maximum of 40kb.
Thanks,
