New Cambrian fossil diversity in China ~518 million years old.

That was dealt with in the article about the find itself - which pointed out that the deposit was undisturbed.

I think you misunderstand me, I meant that scientists have postulated soft-bodied creatures as a missing link explaining the sudden appearance of Cambrian animals. Now they have such soft-bodied fossils! And this makes the Cambrian conundrum worse, because now they can see soft-bodied creatures in that time frame, and they appear to be Cambrian animals, not Cambrian predecessors.

To say the least, this is a bizarre interpretation.

PBS, oddly, also skipped over the fact that the global glaciations that came immediately prior to the Cambrian seemed to have wiped many of the sedimentary rocks off the earth, leading to a sparsity of Ediacaran deposits to start with.

All of which worsens the Cambrian explosion conundrum, the fossils include soft-bodied animals, including jellyfish!

It has long been suspected that the sparseness of the pre-Cambrian fossil record reflects these two problems. First, organisms may not have sequestered and secreted much in the way of fossilizable hard parts; and second, the environments in which they lived may have characteristically dissolved those hard parts after death and recycled them.

Trying to ' argue from ignorance' with hypothetical conclusions does not address the context of the discovery. tabibito answers your question well.

The reality is it is just more information concerning the evolution during the Cambrian nearer to boundary with the PreCambrian.

Not so bizarre when the piece is read in full.

Mudslides covered almost immediately be flood deposits which had the effect of sealing the animals in "cement" before decomposing bacteria could act. Stable geologically which meant that disturbances caused by such things as earthquakes didn't cause losses. There's no problem here that can't be reasonably - almost self evidently - accounted for.

These fossils are ~10 million years older than the Canadian Burgess shale formation.

New discoveries in Chinese formations similar to the Burgess shales of Canada reveal a great diversity of new fossils. Many amazing well preserved fossils with great detail.
