Finder sidebar language problem after El Capitan upgrade

Hi there!

I am having a very annoying problem with the language on the Finder sidebar, some folders like Applications, Downloads and Desktop are constantly changing from English to Spanish in a infinite loop, like 2 times per second. This is very, very, very annoying and stressful.

The first time something similar to this happened was in Yosemite, when I switched the language from Spanish to English (the mac was originally set in Spanish). Some finder windows opened at english and others at spanish. Since the only difference was a couple of folders in the sidebar I didn't bother to fix the problem (I am native to spanish, so isn't a big deal).

But now in El Capitan the bug just become exponential. Every Finder window keeps looping between both languages like crazy. I already check my preferences and I don't have any other language in the Language & Region except from English.

I really hope someone can help me with this problem or at least give me a clue.

Cheers,

Alejandro
