This is resolved in OpenFOAM-7 by commit 8235d2d20c010a4810d059a1a7c8ab414918bae5

Does your OpenFOAM-7 include this commit?

Henry thanks for your prompt reply. I installed OF7 & PV5.6 from the link at OF.org, I apparently need to install as a git repository so I can pull the commits. Or make the few edits in this commit.
Regards, Charlie
