Bukkit interfering with Datapack that loads in structures

The picture shown above is a series of errors that occur when one of the Datapacks installed on the server attempts to spawn in a 'dungeon.' Whenever this error occurs the dungeons that are spawned in are present, but are overlapped several times by Bukkit's "attempt to fix". The end result is loot in chests exploding, as new chests keep replacing it, lagging the server in its entirety. The datapack that this correlates to is called "Dungeons Now Loading" and I have already tested with a vanilla server without the plugins, deducing this is the only problem. However, I simply want to make it so Bukkit won't trigger this whenever a dungeon spawns in.
