Deduplication issue

Quick question, I'm trying to dedupe my library by stacking my duplicates. I'll hold Shift+S to stack as many as possible since I can't see another way to do that and it seems to work, then I'll get "Failed to create stack Immich server error" and if I leave that page and go back, nothing was done. Even if I don't get the error, still nothing was deduped. Is this a known issue?
