The algorithm that was broken is of course no longer used. The point is: Many of these algorithms are rather new. The fact that multiple post quantum algorithms have been broken that were seen as promising shows that there is a risk with these new algorithms. However, it should be said that the broken algorithms were in, let's say, more experimental subfields of post quantum cryptography.
