Thanks for reporting. This was a rounding display issue due to it being a large number. It's patched but I'll have to look into a better long term fix.
Thanks! This one isn't a quick fix. It's an issue with JS. (e.g. this calculation in JS: 0.00001 * 10000000). Perhaps there's a big number JS library that is immune to this.
