Numbers disappear in WeekPlan 2

Hi,

I believe I may have found a bug where when I add a task from my iPhone "Run 4-6mi race pace" it shows up in my browser (Chrome on mac) as "Run mi race pace". It's maintained the priority and roles given but even if I try to add in the numbers for some reason they don't show.  Interestingly it shows fine on my phone and it happens to most but not 1 of the variations of this task I had added through the week.. could it be something I've done? 

Thanks!
