Export Button Not Working?

I was just wondering why the export button doesn’t work for me, is it disabled?

When I click it I get the option of CVS or excel, but then I cannot click either of them. Is there something I’m missing? I could just try to do it some other way but this would be more convenient.

I’m new to this so thanks.

Yes, it’s never worked for me, despite always using the latest version of Firefox.
