I'm seeing a new behavior in 2021 SP0 and SP1 where all of my imported models are translated up some distance whenever I import a new model. These projects are only a month or two old and saving the files doesn't seem to correct the issue. My lights and cameras remain in place though. Each time I add a new item, the models translate upwards, so eventually it's off the screen. See screenshots below.

Is anyone else having this issue? 

Thank you,
