I've found that in figures that I've made that Poser usually appends the internal actor names with :1 when saved to the library. You would think there was some importance to this but I've noticed that deleting this numbering and : has no noticable ill effects on the figure's functionality (such as crosstalk or whatever). AFAIK it's just another one of those weird (and slightly irritating) things with Poser. Maybe somebody like Nerd or PhilC or NetherWorks would know? Maybe Snarly.
