MetroTabControl -1 Index Parametters

[neimex23]

Bug explanation

While testing metroframework I found a problem with the tabcontrol, I think it is a problem in how it assigns the indexes to the tabpages, but recurrently if I modify a tabpage when compiling or editing the tabcontrol collections it throws an error that the parameter in " index" cannot be -1, if the order of the tab page is modified the error stops giving momentarily but if the tabpage is edited again the error appears again.
I try excecute the error in a clean evernoiment but still happens
