I have noticed that when making a DOUBLE structure that I can not use the up function. Let me explain. I have a structure that spans 4 chunks or a DOUBLE and it goes up +6. but when i use this in the json file.

{
"weight":1,
"up":6,
"size":
[
"DOUBLE"
]
}

I get bedrock walls in the +6 section.
like below. I have removed a little bit to show you what happens.

I have noticed even if i use +1 it adds in the bedrock on DOUBLE and TRIPLES. cause I have 2 other structures that are DOUBLE and TRIPLE and they work fine because they do not go above the default.

Is this a bug or am I missing something here?

I am using
MC 1.10.2
Forge 12.18.3.2297
Labyrinth 1.4

I was also wondering if you have more documentation on the replacement section of the json other then what is in the defaults on here.

I have improved world generation in the Labyrinth. The bug with Bedrock walls spawning when a room extends further up or down than default should be gone with the new version Labyrinth-1.5.

I have also added new sections to the Adding rooms.md document detailing the usage of the transformations and replacements sections of the room json files.
