Tilix Quake's placement stuck at top

Issue occurs on Ubuntu Budgie 18.04LTS and bionic-proposed (2 machines)
Cannot change Tilix Quacke’s placement, it is always at the top.

I’ve looked at the 18.10 version of Tilix and the option to change the position for quake has been removed - so am assuming here that it never has worked and the tilix maintainer decided to remove the broken capability instead.
