Bundle in bundle disappeared

I was moving a bundle into bundle and they both suddenly disappeared into nothingness.

One bundle contained 8 maps, one contained 32 prismarine blocks and 2 condiuts and one was empty. I clicked the empty one into the map one, into the condiut one and they disappeared out of my inventory.

I tried shutting down minecraft and the xbox but it was already gone. Please help those condiuts took me so much emeralds to get, I play peacefull and haven't found any fossils myself yet
