QObject::connect: Cannot queue arguments of type 'QQmlChangeSet'

Internal class warning appearing in Qt 5.8 project output:

"warning] <my project name> (kernel\qobject.cpp:102) - QObject::connect: Cannot queue arguments of type 'QQmlChangeSet'
(Make sure 'QQmlChangeSet' is registered using qRegisterMetaType().)"

Question: Currently seeing that a table view I'm using is not getting updated until I resize the window (despite row count being called and having changed..). Is this related? I presume I cannot actually do what the print out suggests as this looks to be an internal class ... ?
