Sounds like you are hearing an incorrect version, but since it sounds fine to me, it's propably a temporary/local clitch in the audio on your end.
The first e is long, though, and stressed and there's a bit of intonation, so it's also possible that you've learned to hear the difference between the two e-sounds in the word but your mind is exaggerating and misinterpreting it for the moment. The thing is called pitch accent.
Here's a similar word (couldn't find renen in forvo) http://fi.forvo.com/search/benen/sv/ Here's ren for comparison http://fi.forvo.com/search/ren/sv/ (couldn't find benen either…) You can hear that the vowel is pretty much the same, but the prosody (intonation, stress etc. are different). Here's a good video explaning pitch accent in swedish https://youtu.be/lXp7_Sjgm34
I read all the comments, can only find everyone hearing it say the same thing as I do. Rihannan. I'm commenting on 2021. We can't all ve wrong in what we here, right? What I was hoping to find in the comments was the correct way to say it if what I hear is incorrect. Please help, tack
Duo doesnt make courses for you only you know many other people probably will use this word when talking about such things as: Christmas, if you own (a) reindeer, talking about Frozen and Frozen2, commicating to Swedish scientists in experiments involving reindeer, seeing a reindeer, or wanting to see/get a reindeer.
