The user is using a Nav Mesh Bounds Volume and a Nav Link Proxy. They are calling AI Move To to navigate to the point, but the Character reproduces extra movement and goes a bit past it. For debugging, they are printing the whole way, and you can see that the penultimate point is further than the one specified, which is why Character returns a little back.
This was reported and tested in 4.24.2 (CL-11100242),. This was reproduced in Main 4.25 (CL-11384700). This works as expected in 4.23.1 (CL-9631420).
Results: The character will first move beyond the destination, then return to the desired position.
Expected: The character stops at the destination.
