Importing from another catalog loses stacking information

Using 'Import From Another Catalog' brings the photos into LRC and into the collection they were in, but all the Stacking is lost! This is a new error introduced by a recent release, since this used to work well. I am using LRC 12.2.1 for MacOS 11.7.4. I created the other catalog on my laptop while traveling, and now want to bring my work into my main catalog on my desktop computer. My work to develop photos starts with Stacking them, selecting the best photo for the top of each stack, and then developing only the top of each stack. Now in my main catalog on my desktop computer, all that work to organize the Stacks is gone! This has now happened twice. It is a big pain, since it is so difficult to reconstruct the stacks. I have had to open my laptop to see how I organized the stacks, then working to reorganize that way in my main catalog. Please notify me when this problem has been fixed – this is a major impediment to using LRC on my laptop when I am traveling.
