Grid Effect - Bug when Property Linking to the Feather /Width refers to Grid Width Property

so when trying to pickwhip in an expression to the Grid>Feather>Width property after applying the effect we get errors as it populates the expression with 

thisComp.layer("Base").effect("Grid")("Width")

which there happens to be the grid width property with that name. I found this out by copying a layer with 'relative property links' and the feather width and height kept populating with my grid width and height values. 

In my attached screenshot you can see the value refers to the Yellow value when i want the green arrow value but i cannot get that to pickwhip. I can get it to link using

thisComp.layer("Base").effect("Grid")(8) // feather width
thisComp.layer("Base").effect("Grid")(9) // feather height

If any reads this and needs a workaround in the meantime. Replace "Base" with your layer name
