Black dot in 'confirmation requested' symbol?

Hi all. Probably not a massively important thing in the big scheme but I noticed today that a couple of my contacts, for which the grey 'confirmation requested' symbol is present, have a black dot in the centre... it's not in the legend.
Anyone know what it means?

 

Hover your mouse over the dot and you'll see an explanation. The dots are usually grey or blue. Either can appear to be black depending on your screen/monitor settings.

 

They are a hidden micro dot message for KGB sleepers Comrade.

 

Now where did I put that cipher?

 

This is the thing - the hover just says 'confirmation requested' like the usual grey dot... but these two definitely have a black dot in the middle. Very distinct from the majority that don't.... so it ain't the screen either

 

Noticed the same thing. Hovering over grey dot or grey dot with black center gets the same response.

 

The same here. Yes weird!

 

Yes same here. Yes strange

 

Perhaps @W1DQ can provide some insight?

 

I too have the same thing. Tried deleting and recreating the record. No effect. Problem remains. Any input as to why or how to correct would be appreciated.

this morning, just opened my QRZ logbook and for (and only) all contacts where I had requested QSO confirmation, same thing, grey dot with inside, on the centre, a black dot.

 

Same thing for me. I just ignored it and thought of it as some sort of update or something.

 

I didn't even take notice of it, but now that you guys brought it up, I checked and I see it as well.
