Describe the bug

When saving my clipboard as an nbt structure, FAWE seems to replace structure void blocks with a random block relating to the structure, but only if the structure blocks cover an entire layer's air blocks.

To Reproduce

1. Build a small hut / structure with open interior
2. Select the hut and fill all air blocks with structure void
3. Remove all structure void that remain inside the structure
4. Copy the selection
5. Save the selection as an nbt structure schematic
6. Load the schematic
7. Paste

Expected behaviour

The expected behavior would be for the structure void to be pasted with OR removed (based on how Minecraft's jigsaw structure saving works - I'm not 100% aware of the block placement result, but I am aware that it should either place structure voids, or nothing - definitely not a random block)

Screenshots / Videos

Example Build

Structure NBT save (after replacing blocks at the door holes and below with structure void)

Loading, and pasting the saved structure schematic.

Checklist

• I have included a Fawe debugpaste.
• I am using the newest build from https://ci.athion.net/job/FastAsyncWorldEdit/ and the issue still persists.

Anything else?

Thanks for taking a look! I hope this gets fixed in a somewhat timely manner if this is indeed a bug and not a misuse on my end.
