Borders have suddenly appeared around data

#1

Hi All

I have developed a new project and out of the blue a dotted green line has appeared around one of the cells. I have no idea how to remove it.
I have attached a picture
Any and all help very much appreciated!

Hi @Steve_BATH, that’s strange indeed! What happens if you doubleclick into that column, is there a formula in that column?
