Bug: Numbers on review functions in one course refer to a different one

Sorry for the awkward title! What’s happening is the following:

  • I use Classic Review in a course (10 words in my case)
  • when I’m done I end up on the main course page (with all the planets)
  • I pull in the list of courses from the left, and select the next course
  • I tap on the four coloured dots
  • the numbers for words to review in Classic Review, Difficult Words etc still are the ones from the previous course, and if I tap on them I end up in the previously open course again
  • I sometimes have to go in and out 3 times until I can review in the new course
  • waiting for 10s or so usually also resolves the issue

Is anybody else seeing this? I’m on the latest app version, and am running Lollipop
