Solitaire Home Story Infinite Life Issue

Tonight I went in to play Solitaire Home Story.  I got my day 7 bonus, it was 30 minutes of infinite life.  I decided I would activate the 15 minute infinite undo I had in the event prize track.  I was playing, no issues.  Then I noticed I was losing lives...which I thought was odd because I know it hadn't been 30 minutes yet.  It appears the infinite life turned off when the 15 minute infinite undo ran out.
