Forums Bug Reports Unset WildCard messes up the variables

I created this alias and noticed that the variables screen looks strange after a while, as shown in the attached image.

alias noticias.unset.num {
var %t $1
while (%t >= 0) {
unset % [ $+ [ $+(*?,news.,%t,*) ] ] % [ $+ [ $+(news.,%t,.*) ] ] $&
% [ $+ [ $+(*?,narracao.placar.,%t,*) ] ] % [ $+ [ $+(narracao.placar.,%t,.*) ] ]
dec %t
}
}
