Resolve 16 Fade handles don't seem to be working

Hi guys,
I'm trying to fade a timeline clip in and out, but the fade handles don't have any effect. It's drawing the ramps on the clip as expected, but it's not actually fading.
I ended up dropping in a couple of cross dissolves to achieve the desired effect, but I'm not sure why I had to.
Any idea?
Thanks!
