Make sure that you select a format type in the "format filter", that's what did it for me! Version 1.2, Godot 4.6.1
ah thank you! yeah very non obvious. probably should default to "all on" 🙃
It was default to all on but it was giving some performance issue that's why I switched it to all off. I introduced a new optimisation system so now it will be all on but default from the next update.
