Something I just noticed today is the copyright at the bottom of the screen on my L3's. The miner software is copyright 2013-2014. So it would seem that Bitmain has been sitting on the scrypt mining software for a while. Just thought I would pass that along as food for thought. 
They just have not bothered to change that.Even my S9s and R4s say the same.
My guess is they copied the same miner GUI page from miner to miner and they don't have someone on staff actually updating it.
