I had two 'search folders', and tried to merge them, now folder structure is broken

[ponyportal2]

I had two 'search' folders named exactly the same (not sure how that ended up), and tried to merge them,
And it can't find remaining 'search' folder(package) now in imports, though it exists
Both folders were marked as sources by the way.
