EFDC8.4 to EFDC 10

I’ve switched my model from EFDC8.4 to EFDC 10. There seems to be a problem with the boundary condition definition in version 10 (with the “Elevation Specified” boundary). I had the Elevation Specified" boundary to keep the water level matching with the observations for the lake. Now, with version 10, the water accumulates in my lake and won’t release from the dam. Does anyone have the same issue?
