Zero velocity on some beam nodes

This file shows v=0 on node 2 even though its displacement is changing and there’s a non-zero velocity one node 1. I wonder if this is what’s supposed to happen or it’s a bug? I can’t find anything about it in the manual.

*NODE
1,0,0,0
2,0.1,0,0
*ELEMENT,TYPE=B31,ELSET=Default
1,2,1
*MATERIAL,NAME=Material
*ELASTIC,TYPE=ISOTROPIC
10000000000,0
*DENSITY

*BEAM SECTION,ELSET=Default,MATERIAL=Material,SECTION=RECT

*STEP
*DYNAMIC
0.01,0.1,0,0
*CLOAD
1,1,0.01
*NODE FILE,GLOBAL=YES,OUTPUT=2D
U,V
*END STEP

It seems to be a bug. There should be a non-zero velocity in the first direction reported for node 2 and Abaqus calculates it properly when I submit this input file in it.
