Context of 'Referrer' in Clarity Reports

Question

I understand what a referrer is, what I don't understand is why this is listed there.

So this is showing google.com 655, google.com.au 90, uhm and if, but if I click on this. 0:17 I mean I understand Facebook, so these are all the sources of traffic, essentially, or where they're coming from. Now if I click on that, it shows me .com 655, 90, so it's showing me the same figure.

So why is that even listed there? That's actually quite confusing.

I mean 655 and 90 does not add up to 718.

So can you please explain what that means? Why is that listed?
