This is a weird one!

My normal directory comparison setting is to use the "Show Only Differences" filter and "Grouping By Status". But sometimes I need to see everything (rather than only the differences), so I change the filter (via the toolbar) to the "Show All" filter.
But when I do that, files that happen to fall into the "Added" (or "Deleted") status group, disappear! They're not shown at all! They disappear from the directory comparison display!
If I leave the filter set to "Show All" but change to "Grouping by None", then the files that exist in the one directory that do not exist in the other appear in the comparison display again!
What is DOUBLY WEIRD is, when the problem occurs ("Show All" + Grouping By Status"), if I scroll down to the bottom of the comparison display, there seems to be two "phantom" groups displayed with no files shown in either group! No filenames are displayed at all! The screen is BLANK in those two groups (where filenames would normally appear!)
VERY weird.

NOTE: I am unfortunately unable to create a small reproducible test case for this bug. I don't know why. When I try to create a small set of directories with the (supposed!) same conditions, EDP behaves correctly. I can only cause the problem to occur with my project's live directories, which are unfortunately very large. I don't know what the attachment limit is, but the .zip file that reproduces the problem is 43.1 MB in size. I am going to try to attach it to this problem report.
I would have attached screen shots to illustrate the problem, but your board will not allow me to attach all 5 of them. It attaches the first 3 and then the others get an error. So you'll have to look at them in the attached .zip file (which contains the two directories, all 5 screen shots, an export of my options as well as an export of my settings).
Thank you for any help you can provide on this VERY weird bug.
It's really causing me serious grief.

OKAY, THE .ZIP FILE IS TOO LARGE TO ATTACH.
So I've temporarily uploaded it to my web site. You can download it from there:
