Problems with accents (tildes) in Manjaro

Hi! Since the instalation of Manjaro o nmy laptop ive been experiencing issues related to the correct writing of vowels with accent. Although they keyboard correctly writes all the keys in my keyboard, the accents go separate from the vowels as this:

´a e 'i ´o u

They do not mix with the vowel but they are separate from them. The language of my Manjaro XFCE is spanish, as my keyboard, and I do not know to correct this problem could you please help with this one.

I would Appreciate it.

Thanks!!
