Somthing suddenly happened with my GRID in Miro. I Think i moved it…. And then suddenly all the shapes changed size. Why does this happen? 
This is what is was privously:

 

I can’t undue it…. and now need to reconstruct it as a whole… wasting my whole day.
Edit: I did copy it from an older restored version.

is there something i am doing wrong using the Grid?
