I dug into this a bit more as I've recently gone from using source builds on a Mac to a rasberry pi / stellearmate via the standard repositories.
It appears that for the AP driver the latest pi repository is @ 1.7.3 found via.
Looking this up on
launchpad.net/~mutlaqja/+archive/ubuntu/ppa
for indi-bin yields a date of 5/25/2018 which should encompass the AP driver updates.
So if you had done an apt-get upgrade I would have thought you would have had the AP fixes.
You might try the above apt-cache show command on your system and see if it says 1.7.3
