We have a smart group which returns 1,521 records. One contact which ought to be appearing in it isn't. When I go in to the smar group settings there is an unfinished selection line, when I delete this the search then gives 1,552 records, including the one that we saw was missing. I then take the action of updating the smart group but when I go back into the manage groups and click on contacts it is once more back at 1,521 with the one we want missing. It is very possible that there is a step that I should be taking which I am not. Can someone point me in the right direction?
I am running Civicrm 5.13.4
