Jigsaw block generation is offset by a block and ignores direction

Structures generation behavior from using the jigsaw block is not behaving as expected.

I started using jigsaw blocks and was following a tutorial, but I started running into a problem where the generated structures were offset. Using the generate button on the jigsaw block, the structure generated would be place 1 block lower than the intended placement. And the jigsaw blocks would not align properly.

I did this a few times with other examples and got the same result

Steps to Reproduce:
1. Create a custom datapack structure with jigsaw block connectors
2. Attempt to generate using a jigsaw block.
