Litematica printer does not print walls not connected to something

[LeoParte30]

I've got this temple with columns made out of walls, only connected to the ground and each wall connected with the others, and litematica printer does not print them, i've placed them manually in the screenshot and they appear orange, like placed wrongly, i think it's a problem with stacked walls with the value "up:true" because it's a column of walls, please fix
