Copper golem does not stack items.

I was recently using the copper golem in my world (Minecraft Preview, Windows 11, Bedrock) and I encountered an issue. I had a cauldron in a normal chest and I put it in a slot that wasn't the first one. I put another cauldron in a copper chest. The golem took it and put it in the empty chest in the first slot. It wasn't stacked. This was a thing I was excited about, not using my mouse for chests. Instead the golem puts it in the first slot available, not the one where the item is. This is very frustrating and a exciting prospect of the golem. It won't be as good if it continues this. Thank you and please fix this.
