Update The Models with New Scale In Elefront When Using Blocks in rhino

Hi,
I Have some blocks in Rhino and then import them to Grasshopper Using Elefront. then I realized my objects were smaller than I except, So I go back to rhino and Scaled Up all of my Blocks manually, But after that, the grasshopper couldn’t recognize the objects in their new bigger dimensions. it seems the blocks don’t update after the scale command in rhino. in “block manager” command I use “refresh” but nothing happens. the “Update” checkbox is Unselectable and I don’t want to re-assign the blocks because it’s too many blocks!
how can I fix it?
