Invalid selection, please try again

I always get this error when I try to calculate. I tried to change commas and dots and also the OS language.
Any ideas about what can be happening?

Hi, sorry I haven't been able to work on this recently. I'm not really sure why it is not working unfortunately, try copying the values 51.519586,-0.14883 and 51.499339,-0.107546 and paste them in manually to see if it's just the selection tool that's bugged, these work for me.

Hope this helps.
