Moving stacked photos around in grid view

[as73]

I'm using LR Classic 14.3 on a Mac (M1 Max).

Recently I shot something where I ended up shooting the same angle of a building at different times of day.

I organised the images (brackets of each angle) into stacks to make it easier to sort through but now I find that when I move the stacks around (sorting them into a "custom order" in Library grid) if one stack ends up next to another stack, LR will combine both stacks together....? If I move the stack between two unstacked images it will move and keep the proper stacking of the images. What am I doing wrong here?

Any suggestions?

Maybe the two stacks just touched, and so Lightroom thought you wanted to merge them. Try this: move the stack and keep one unstacked photo between them. You said that worked. Now move the unstacked photo to the other side of the stack, so both stacks are now next to each other. Does that work?

When you move a stack BETWEEN two other stacks you have to make sure neither stack you are moving between have a BLACK BOX around the stack.  That will add the moved stack inside the stack with the black box.  When there is a BLACK VERTICAL LINE between the stack then the moved stack will end up between the other stacks.

Thank you, I think that's where I made a mistake. Seems to be working fine now with the way you described.
