Editor forgetting tab locations

Something changed in my Editor as now everytime I reload Unreal, the location of the Place, Outliner, Debug Log, etc tabs revert to their default settings. Is there an option somewhere so it’ll remember the last location I moved them to?

Finally found a fix for this (based on a random tweet about the editor)… I turned off “Enable Legacy Editor Mode UI” under User Interface in Editor Settings. Now everything is back to where it should be.
