Simple Xdmf file appears as empty multiblock on Paraview 5.9.0


I am trying to open a simple Xdmf file in Paraview:
slice.000000.h5 (54.0 KB)
slice.000000.xmf (1.9 KB)
This works as expected in version 4.0.1, but in version 5.9 the dataset appears as an empty multiblock.
What changes do I need to make in the Xdmf file?



Seems to work well with the XdmfReader (not with the XdmfReader3)

Also works for me, thank you for your reply.
