wrong time shown by re-interventions

Hi,
I've noticed that when multiple re-interventions are triggered, the timer displayed on the screen with “Continue to [app]” button shows the wrong amount of time passed.
For example in the image I had first a 3 min intervention and then a 1 minute re-intervention totalling at 4 min, instead it says “last usage: 1 min ago”.
I think it should be fixed so that the page displays the real amount of time passed or even something like: “you said 15 min, now it’s been almost 45”.
