"STRING FORMAT ERROR: invalid format string" in Atlas Passives Tree (¿Spanish only?)

Hi, it's the first time I post an error/bug report, so here is my contribution.

The text in the Atlas Tree's notable passive "Buried Knowledge", at least in the Spanish version, shows an incomprehensible information. I detected this months ago in the Sentinel League, but I didn't give it importance because I wasn't dedicated to making Expedition content.

But now with the release of the new League, I want to do Expedition and I saw that the text remains the same, and I can't even realize what it does. Yeah, I could search the PoE Wiki...¡but I want my spanish client be correctly spelled! :-)

Thanks in advance.
