Nginx Amplify is showing me multiple different versions of Nginx on a specific server, i had 2 versions showing up there and i just upgraded Ninx and now 3 versions show up there.

The exact location where this is displayed,: Graphs -> Systems (click on the server) -> then under the server name there is the nginx version (next to the "System" tab), it has an arrow there and clicking on it shows the 3 versions.

Why is this happening and how can i remove the other two that are clearly obsolete?
