I'm sure that I just have some setting screwed up, but I can't get a number of things in the filmstrip area to work correctly.
1. Sort By Filename, or by added time, or by flag don't seem to work.
For example, If I sort by flag, I would expect that all the flagged images show up adjacent to each other at either the beginning or end of the filmstrip.
Similarly, by filename, I would expect alphabetical order.
The problem is that I did a shoot yesterday where the camera clocks were not synced, which when I sort by capture time, I have a lot of images that are interlaced.
2. I can't get stacks to show up - not matter what I do, nothing stacks in the filmstrip window.
This is Lightroom 5.6 and 5.7
Re the stacking: Beware that stacks are specific to the folders or collections you make them in. So if you stacked the photos while in a folder but then show a collection in the filmstrip, the stacking won't show up.
