Here is a grounded board (upper left), an assembly workplane (offset from the grounded board), and a copy of the grounded board (lower right). The copy is flush constrained on two origin planes, and the final position determined by a symmetric constraint. It is correctly placed but the a DOF marker suggests it is free to move along one dimension:
The DOF display is the same if this constraint is suppressed, and in that state the DOF is expected.
Even more confusing, if instead the copied board has the same origin plane constraints, but the symmetric constraint is replaced by a mate constraint to the same workplane, the DOF indicator is gone:
Why the difference? The workplane is a symmetry plane and I really want to use the symmetric constraint, but the pesky DOF indicator is a concern because I don't understand it. It is either a bug, or I missing something fundamental.
kelly.young has edited your subject line for clarity: Unexpected degree of freedom after symmetric assembly constraint -- help!!!
@Anonymous I followed your workflow and can verify that when you add the symmetry constraint the DOF glyph remains in 2018 initial release version.
What update are you on?
The functionality of the constraint works it's just the little green arrow that doesn't go away.
I have forwarded the information to the development team for further review.

Here is a more noisy version of the same problem:
The board with the rotational DOF has two symmetric constraints, and one origin plane constraint to fix it's position.
