Comments:

Something strange happens at t=0.6s where the ohmic really comes up and the LH goes down. It looks like it may be the high temperature at the edge increasing the damping farther out, but tough to tell. Try a rerun w/ the new switches and see what happens. Keep PLH the same. For more information about the run see the input namelist.
