Clicking on tab on top of grid view is not sorting data alphabetically

[ChrisM]

Hi

I can't seem to get data to sort alphabetically. Here in this video, you can see I am trying to sort by camera model. My expectation is that it will sort alphabetically, and all the iphone images will gather together, then the L2D-20c. I even tried searching in the search bar to see if I could isolate a specific camera. Am I doing something wrong? Or is this a bug?

PS- It says my video of my screen is too large to upload. So here is a link to it: https://www.dropbox.com/s/fc51yaeutru7o ... h.mov?dl=0

Another matter if you double click the divider line to expand it to max. then the text does not update to display, if you drag the divider it does.
