Outline duplicates files when Editor is split

I’m having a weird issue with the Outline in which when the Editor is split - the filenames duplicate. And it’s just the filenames, i.e. you can’t expand/compress them, or remove them for that matter. This really curbs workflow especially when working with a lot files in a split Editor window. So much so that I have stopped using the Outline and am forced to scroll through the files …

Here’s an example when I have multiple files opened in a monolithic Editor pane:

Now when I do Split horizontally (same happens for a vertical split), the Outline gets messed up like so (notice that only every second entry can be expanded):

The messed up Outline persists even when I close the split. It’s corrected if I reset Spyder.
