Append Attributes filter only keeping one data array

ParaView for Mac 5.10.1

I have two XDMF files, each containing a unique data array. The first one contains an array “t”, and the second contains the array “domain_labels”.

I am trying to combine them using the Append Attributes filter. I select both inputs, apply an AppendAttributes filter, but the result only contains a single data array. It seems to contain the array of the object I select first. If I try clicking “Change Input”, both the sources are selected as I expect. I try reselecting but no matter what I do, it only contains the data from the object I select first.

Hi @atompaul ,

AppendAttributes requires both sources to have the same number of cells and points. Is that the case here ?
