Steps to Reproduce:
1. Pick a structure block and place it somewhere.
2. Use it to import a structure to the world.
3. Use it again and import a different structure this time.

Observed Results:
The second structures (and later ones) will not be imported, instead the first structure imported will appear again, resulting in the import feature working only one time per world.

Expected Results:
Every different structure should be imported, not only the first one.

Importing structures/entities to new worlds only work one time after that one time any other structure you try importing to that same world will instead result in the original structure being placed again even when you delete the file of that original structure I'm going to include 2 worlds one for exporting structures and the other for importing.

Incase anyone doesn't know how to use the structure block:

1. Go up to any of the 3 structures & interact with the corresponding block, it will be on save tab by default, name the structure and click export (this allows you to save it as a file on your device)

2. Go to the second world interact with any of the structure blocks, go to load and click import, click the file you saved originally, then click load

By doing this multiple times you will quickly learn it only loads the first structure imported to the world no matter how many times you click a different file, not even deleting it works
