Unable to click map with Boss witness by Maven

Bug Report ID: #4,291,627,699

Maven grabbed random boss witness on burial chamber(uncompleted), now I am unable to click on it to complete it. following imgur link just shows atlas and uncompleted but witnessed boss. Assumption is it will be good after I completed the invitation, but I should still be able to use the map currently. https://imgur.com/a/VUv8Did
