Design Study Not Re-Meshing Between Scenarios With Mesh Control Parameter

I'm attempting to use a design study for a mesh convergence plot. I set up a mesh size parameter at discrete sizes and linked it to a mesh control which is applied to a fillet. The simulation is not re-meshing between scenarios and each scenario has the same result and mesh.

I've tried linking the parameter to the mesh control via the parameter window, I've also tried manually linking the value in the mesh control itself, but neither of these worked.

The design study is able to re-mesh between scenarios when the parameter is applied to the global mesh, but this will cause long simulation times on some of my larger parts.

Any help would be appreciated, thanks.
