Conditional Formatting misbehaving

[Stefek1974]

I've googled this, I'm sure it's obvious, but I can't work it out.

I pull in a RAG status from an Excel file. I replace, Green with 1, Amber with 2 and Red with 3 so it's simple to conditional format (well it should be). 

This is the conditional formatting I've set up: 

But strangely this is the outcome. Some of the ones are treats as if they are twos (screen shot below). I've checked and there's no additional spaces with the Greens in the original file so I've no idea why it doesn't recognise three of the ones as ones? I'm sure it's me being stupid but does anyone have any ideas? Thanks in advance for any help.
