On view menu, two "bara de estado" (status bar) appears, where the first is for the status bar (ok) and the second is for the menu bar (with Ctrl^M hotkey). Regards.
It seems it's still wrong[1]. As translations are handled via Transifex, I guess you should contact the translation team[2] and ask them to fix this. 1 - https://www.transifex.com/projects/p/thunar/viewstrings/#es/master/13935802 2 - https://www.transifex.com/organization/xfce/team/16840/members/es/
Closing. Please do report translation mistakes at the proper place (see comment #1).
