I appear to have a similar issue, though I believe the bug description is rather incomplete. So here's my experience: It appears that we cannot stack items from that come from different conditions. I.e: we cannot stack "Stone blocks" that come from mining with a "Silk touch" pickaxe with "Stone blocks" that come from smelting, or we cannot stack "cooked salmon" cooked by a "fisherman villager" with "cooked salmon" cooked in a furnace. You may see this comment on other similar threads. Thank you for reading. (Minecraft for windows 10)
