Copper Golems only putting in one item in any given chest

I turned on experimental features on to see the copper stuff. The Golems are without a doubt adorable to watch. However, when they sort, an issue happened. They only put in one item in any given chest. I place a new chest, completely empty, and a golem puts in item inside. No biggie. But after one item is placed inside, things went downhill. It comes back and opens the chest, but never places in the next item. It just ‘shrugs’ and closes the chest. It repeated this over and over until I gave up and ended the process. No matter how many chests I place, only one is placed, and not a second item is put inside. I am aware of experimental features and that bugs and issues may occur. Please fix at your earliest convenience. Thank you!
