If I'm not mistaken when you dupe something that got buttons. These buttons count as bimoetric scanners. So let's say my dupe got 2 buttons and 4 bio. After pasting the dupe it will say I have used my 6 biometrcis already. Will try again once I get home and see if that solves the issue.
Also I posted a bug report about it, will update the report if this fixes it.
It's 2019. Enough with this already please.
