Structure blocks only load the first loaded structure and not later imported structures.

.mcstructure (1)

.mcstructure (2)

.mcstructure (3)

(1), (2) and (3) are all saved under different names in different directories.

After opening a new instance (my world), and giving myself a structure block set to load, importing structure (1) works as expected. When attempting to load import structure (2) however, only import structure (1) loads. Same for import structure (3).

Attempted fix: duplicating and launching (my world) under (my world.1). Attempting to load import structure (2) has the same effect of loading import structure (1).

When creating a new instance however, import structure (2) loads fine, but then import structure (1) and important structure (3) load as important structure (2).
