Hi. I am having trouble with the folder structure.

Question

I import my pictures like probably most Lightroom users.
They go to:
Pictures / (Year)  / (Subfolder name crated checking "Into Subfolder" during import)
Recently, after upgrading to Yosemite, when I import to this structure, Lightroom creates a folder visually outside it. Above, the "01_Sao_Paulo" folder should appear inside 2015 while "12_Atacama" and "12_Hasselblad" under 2014. The right folders were actually created when I check them in Finder.
And when I try to move the folders under the right folder structure, Lightroom recognizes  that the folder already exists.
My question two questions are:
1. How do I make the folders appear correctly under the right folder structure?
2. How do I make Lightroom stop creating the folders outside the structure on my next imports?
Thanks for any help.

Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - rebuild your iPhoto library database
