Also where it says Server & Address, yours will list the default DNS server that it is contacting to get the record from (it's most likely hosted by your internet provider).
I experienced the issue a little while ago and I decided to try and turn my firewall off and see if that affected anything, didn't seem to fix anything so I turned my AV off as well, didn't seem to make a difference either.

My apologies for not replying for a few days, but I hadn't encountered the issue till just now, so I couldn't run the comparisons till now. I've attached an image showing a before and after comparison, the first set of results are during the issue and the second set are after I disconnected and reconnected to my network.
