cant print with litematica printer (modrinth minecraft 1.20.4)

[bodiegarde]

I'm currently using modrinth minecraft 1.20.4 i have updated the mod to the latest avable version from GitHub as of 7/26/24.

I'm encountering this weird problem when i try to use the printer it refuse to place blocks. i have used default hot keys and tried remapping them. i do not know if I'm doing something wrong or if this is a bug. all i can say is when i enable printing it refuses to place blocks.
