Everytime I import tabs it will come with the linked notation at 2 different octaves and I can't change on without other. Images and MSCZ included

Sorry, yes, that's what I was pointing out (trying and failing to, that is :-). When I saw that they were not linked, I was thinking that they had created that second staff separately as a guitar, but no, it's a piano as well.

For the fun of it, I tried creating notes in a guitar tab staff and changing it to piano. As one might expect, it changed the style of the staff to "Standard".

OP said they created this by importing XML. Perhaps you could create such a thing by directly modifying the XML? That's WAAAY outside my knowledge though.

No, "Raquel" in English. See Raquel Welch versus Rachel Ward, both actors. Names don't translate; they just are!

I'm "Jeff", even in Germany where the equivalent would be something along the lines of "Gottfried". And Jojo is "Joaquim" (I think?), for which the English equivalent would be "James" (???). But see Joaquim Almeda and Joaquin Phoenix, two more actors.

Sorry Raquel, I had assumed that your name as actually "Ruben", usually a male name. And "Remus", in America, is almost exclusively associated with "Uncle". ("Uncle Remus" is a character from an antebellum anti-slavery novel, which was picked up and bowdlerized by Walt Disney in Song of the South.)
