I was going to practise my quickness uptime on power quickness scrapper and ran into this same issue; I can confirm that it is removing one stack of all player-applied boons each interval as I swapped to my firebrand to see if it was a me issue and not a bug. Mantra of Potence applies 5 stacks of might at once, and I will watch it tick down to 4 and then 3 before it expires naturally, as it doesn't last long enough for this bug to remove every stack individually.
