We have a user who is not seeing data that exists in a column in the Web Client, but other users can go to the same exact folder and see the data in that column when choosing it from the picker.  This is data visible to her in the fields area in the right pane and I am certain the column has the correct field chosen as this is the only field by that name that exists in the repository. I asked her to remove the column and add it back, but that did not fix the issue.

See the screenshots below. The blank column in her view, below that the view showing data that exists in the field form the right pane, below that my view of the same folder.
