libritts: AssertionError: No recordings left after fixing the manifests.

When I'm preparing datasets of libritts, I run into this issue:

I've searched up for this kind of issue and I found a similar one:
lhotse-speech/lhotse#989

Seems that downloading libritts with lhotse would cause similar problem. Anyone got similar issue? Thx!
