2-way FSI, transient structural coupled with CFX, ANSYS academic 18.

Meshing and setup etc is complete, however the system coupling fails. When I click "display validation failure", the response "not all participants and system coupling have the same analysis type."

In system coupling: I have set Setup > Analysis Settings > Analysis Type to "transient" (it is backgrounded with yellow, for some reason)

In transient structural: Model > Transient > Analysis Type set to "transient"

In CFX: Simulation > Flow Analysis 1 > Analysis Type > Basic settings > Analysis type is set to "transient"

Now this looks like all my ducks are in a row, yet system coupling insists the various analyses are not the of the same type. I have refreshed, updated and solved everything with no apparent errors in structural and CFX.
