Help!! My sim won't clean up any dirty dishes!!

I have tried so many times to get my sim to clean up the dirty dishes lying around the house - And they just won't do it!!

I've then tried to drag them to the sink/bin but it won't let me select it?

I saw an old thread where someone said to try and switch households (which I have attempted) but still won't work (in either household)

Anyone got a fix for this?
