in survival mode,when the schematicannon duplicate an architecture，if a bock not filled with water has "waterlogged" property and the block is attach to the water source，the water source will not be duplicated and the block will filled with water..

Can you provide a schematic file that causes this issue? I'm not sure I fully understand the problem

This is a vanilla bug: https://bugs.mojang.com/browse/MC-130584

This is still not fixed. Enclose a water block with trap doors, and make a schematic. Upon placing, water spills everywhere because it has leeched to water-loggable blocks. Vanilla bug says its been resolved... Not sure why this is happening yet.
