The construction diagram highlighted using //sel cyl is inserted without air blocks

Describe the bug

Hello everyone, I have clearly shown the problem in the video. I selected the building and copied it using //sel cyl, using the usual //paste - everything is inserted as it should be, but when creating schematics, for some reason the building is inserted without air blocks inside. How can I fix this?

Watch the video at the link

To Reproduce

1. Select //sel cyl
2. Select all buildings
3. //copy
4. Try //paste
   Further
5. //schem save name
6. //schem load name
7. //paste
   See the difference

Expected behaviour

I need the schematics to be inserted with air blocks (just like the construction is inserted using //copy and //paste)

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?

Start by reproducing the difference between //copy and //paste and the //schem save/load and paste sequence using //sel cyl, then inspect the supplied FAWE debugpaste and video. The fix is complete when a saved and reloaded schematic preserves the selected construction's internal air blocks in the same way as direct copying and pasting.
