Can't adjust frets properly

[wrathfulwraith]

Okay, I know I've been posting alot lately, so for starters I hope I posted in the right section, lol.

anyway, I'm charting a song that's in drop c...imported most of it from a guitar pro tab but it needs alot of polishing and i'm working on it, however, I just noticed while adjusting the solo parts that if I attach a note anywhere on any string and set the number of the fret higher than the 17th fret, it'll become an X as a muted note instead.

 

I'm pretty sure I probably messed it up somehow, not sure how though, any help would be appreciated greatly.

 

Thanks in advance.
