Lightroom Classic not finding photos in closed stacks

I use the stacking function of Lightroom Classic (version 13.4 on MacOS Sonoma 14.5) to collect different views and versions of the same art object. Collect objects of the same place in folders and subfolders by type. I may have older photographs stacked with newer ones, one of the newer one on top of the stack, but references in my notes may still refer to the older photograph.

Now if I search the photo number of the older photograph within a certain place with all photos in subfolders shown. The photo numbers within stacks are only found if I first make sure that all stacks are expanded. This is valid if I search from "all photographs" (the entire catlaogue) or any of the subfolders with all photographs within that shown (the full number apparent in the folder section).

Since classic shows the full number of photographs contained in the catalogue or the respective folder (including its subfolders) in the folder section, but then does not consider all those in stacks when I do a text search, I consider this a bug.

It cost me a few hours (and some panic) to relalize that I have not lost those photographs I was looking for ...
