Report txt files for (Sum) Phase displacements have no data

I am trying to export results from a model in the form of txt files (Report) for further post processing.

When I extract phase displacements or Sum phase displacements of Plates, the results come back without data (N/A).

See below the txt file outputs for the same phase:

..._ Table of total displacements.TXT

..._ Table of sum phase displacements.TXT (Same issue as with Phase displacements)

Am I missing something? Is there a (direct) workaround to extract the results I want? 

Thank you in advance
