A different division of Marvel does the TV shows. Marvel Studios does the movies, but Marvel Television does the TV.
Based on the fact that the events of AoS are never mentioned in the movies, I've never considered it canon. Not only that, but regarding Coulson being alive, Joss Whedon said he's still dead in the movies as far as he's concerned. I'll chalk AoS up to being a different universe.
Wow... I hate it that the Marvel Television Universe has ignored MCU events, and yes indeed it is lazy writing and a lack of communication between studios. Not sure why parent company Disney ever allowed that inconsistency in the timeline to occur.
