by using the command / testforblocks to check if the box with the content in the destination and the starting site are the same, the command shows that the blocks are not the same, if I remove the contents from the crates and check the empty crates, the command works normally. It is the same with all blocks that have the ability to insert something into them. feeders, dispensers,shulkerboxes, etc. (the pictures show Polish, I'm from Poland.) It's all on the net on 1.19.30.22 but I didn't have this option to choose from.
