Sorting In Perspective Tables In version 8.0.15

After recently updating our ignition 8 installation, I am unable to enable column sorting in any perspective tables. According to the documentation I should be able to sort by double clicking a column header if the headers are enabled and sorting is enabled on that row. Both of those settings are set to true but sorting is still not working.

Thanks in advance.

This is still a problem in 8.0.15. Is there a fix?
