Road-Schematics not working with 'paste-road-on-top' enabled

Describe the bug

With my current setup, I am only able to use road schematics when setting the road to a height of 0 and disabling this option. But I want to use the signs and put them on the slabs...

When I flip this option, the schematic is not being used and instead an ArrayIndexOutOfBoundsException happens, before the world settings are displayed in the console (They are still displayed). It sometimes refers to the number '-63' if that can help.

To Reproduce

1. Use a road schematic via templates (my setup)
2. Check, that the schematic is generating with the option set to 'true'
3. Change the option to 'false'
4. Check, that the schematic stopped generating with the option set to 'false'

Expected behaviour

The Schematic should be used and override road blocks (instead of otherwise, where the street has to be non-existent to make the schematic appear)
