Treating multiple .xmf files as a time series

I have a series of .xmf files (*-000.xmf, *-001.xmf, *-002.xmf etc), each of which reads 1 timestep from a corresponding .h5 file. Paraview is not recognising these xmf files as a time series, nor does it recognise the time in each individual xmf file. Any suggestions why this isn’t working and how I can fix it?
