Cannot open fileseries in ParaView 5.4.1

Dear All,

I have a fileseries for a lammps data file. When trying to open them I selected File/Open and I see my lammps .dum fileseries with ‘Type: Group’. I can select each individual dump file within this group. But If I just select the entire group, and try to load it by pressing OK, it will only load the first .dump file of the group and no more.

I have tried to individually load all files, but instead of creating a dump* source which contains all the timesteps, it will create N different dumpN sources.
