Structures cannot be saved via commands or redstone powering a structure block

When saving a structure, using a command block or a Redstone link to a structure block does not save it permanently. When reloading the world, the structure will not exist. The structure WILL save if the player manually clicks save in the structure block.

Steps to Reproduce:
1. Use the /structure command to save a 1x1 area OR activate structure block using Redstone to save a 1x1 area
2. Load the structure and notice it loads properly
3. Leave the world
4. Rejoin and try to load the structure
Observed Results:
The structure does not exist
Expected Results:
The structure loads.
