Advanced sub-schematics won't spawn other advanced sub-schematics sometimes

[KingofAnomaly]

Describe the bug
Advanced sub-schematics don't attempt to spawn in other advanced sub-schematics sometimes leaving the signs behind.
I have gotten it to work on smaller structures so I'm not sure what is causing it.

Steps to Reproduce
Have a large advanced sub-schematic with other advanced sub-schematic signs.

Expected behavior
After the sub-schematic spawns it spawns the next set of sub-schematics

Environment Information:

• Minecraft Version: 1.18.2
• Spigot Version: 1.18.2-320
• Custom Structures Version: 1.8.1

• Async World Edit Version: 3.9.4

Additional context
I am trying to make a dungeon with randomized walls and decorations. There is a main chamber which is the structure schematic and I have sub-schematics for paths expanding out from the center, sub-schematics for different wall variations and wall facades. The paths should be placed then the walls then the facade.
