Make a debug world, and use the command below to teleport to the barrels.

/execute in minecraft:overworld run tp @s 209.10 73.20 29.87 844.68 56.05

Notice that the barrel keeps making its "closing" sound.

This seems to be an issue with barrels constantly setting their "open" state to false.

/setblock ~ ~ ~ minecraft:barrel[open=true]

Using the above command will make the barrel close, unlike other blocks that keep the state specified when placed with /setblock.
