Spec-Driven Piping: Color of Pipeline not Changing when Editing Piping Specification

As shown in the image below, I have defined a pipe spec that has a particular color assigned to it (in this case, green). This spec is shown to be this way in the associated Pipe Spec Directory file as well. However, despite all of this, the pipe keeps showing up as blue! I’ve updated the pipe model and regenerated the assembly but nothing seems to work. What might be causing this issue?
