So i was building a schematic with a composter with the state of a compost value level 6, I had already placed that composter but in the functionality of the composter there was no reason for me to fill it so i kept it level 0. I also needed other composters in the build so i checked how many i still needed to place in the active schematic material list and saw i needed a few after placing all of them i had one composter left and couldn't where and i thought "if i remember correctly schematic verifier has a feature to highlight where it is" so i checked schematic verifier and saw that there were actually no missing composters while my material list did say so, the schematic verifier only said that there was a composter in the wrong state, and seeing that means that the material list wrongly refers to this block.
A clear and concise description of what the bug is.

To Reproduce (if not clear from the description already)
Steps to reproduce the behavior:

1. "Have an active schematic open that contains a block with a specific state like "on" or "off""
2. "Fill this block with the correct block but in the wrong state"
3. "Go to material list of the active schematic and it will show that you are "missing block" this specific block.

This was recently fixed (or at least a config option was added for changing this behavior) in this commit: bbaff69 for 1.12.2. So the fix/change will come to the other version with the next merge from 1.12.2 at some point.
