Trouble exporting census of dissapeared, Export do not match selection

Hello
I've done this selection from census of disappeared that returns 114 registers:

When I try to change a field and propagate it doesn't show 114 registers but -1

I found this suspicious so I did'nt do anything, and then when I was back to the list, all the registers with no filters were returned:

If I apply again the filter and I try to export it, it also shows all the registers:

So I cannot propagate neither export this selection of files.

Please help. Thank you!!!

I am afraid thas was a network issue, as after a while I was able to export it with no problems.

So, nothing to worry about!
