cv 16 won't change back to notes

[chriswest]

On the cv 16 pattern screen I have come across the issue where if I surpass the note values + hexadecimal values by mistake and the tracker reads one of the internal envelopes + then I switch back to note values the tracker will cease to read any new note values.
it's like it's stuck or something. 
Also there is a mystical "^" symbol next to the cv output destination indicator of the corresponding column. what does this mean? 
In order to get rid of the issue I ended up restaring the project. 

Anyone know what's going on in this situation?

   

thanks
