Inactive DOF ABAQUS

[Entherm]

In the Abaqus, I have a beam and column made of shell elements (S4R). They are connected with Tie constraint. When I run the analysis, there are node sets under "WarnNodeBCInactiveDOF" and those are the ones at the connection between beam and column. What might be the reason for this? This is creating a problem with my results.
The nodes where I applied boundary conditions are also in the node set.

 

[FEA way]

This warning might indicate overconstraint in the model (several constraints/BCs applied to the same set of nodes).
