Astroberry/Kstars/Ekos alignment problem with near due south stars

Hello,
I have a nicely working imaging system controlled through Ekos. I can get the plate-solving and alignment working perfectly for, say M101 (nearly straight up at the moment) to within about 15 arcsecs. BUT when pointing at star WASP-43 (to record a exoplantery transit) that is presently nearly due south and close to the horizon, I find the following:
We ended up using the handset to position the scope to allow the transit to be recorded. So the telescope can reach this target - the question is why is doesn't get this automatically?
The set up:
We've tried various different batteries to make sure the input voltage to the mount is 12 V. Still get this problem. We've slackened the cabling to ensure there is no tightening at the extreme orientation needed for WASP-43. We've re-balanced the system. Nothing seems to solve this issue.
The system then works perfectly for, here M101, slews, aligns, and guide allowing 10 min exposures.
Any one have a clue why due south is such an issue? Or has seen similar behavour?
Peter
