PhD chooses a bad guide star--and then loses it

Sequence Generator
1

I’m using SGP with a Celestron C9.25 on a CGEM mount with a Lodestar X2 on my guidescope. When I start a sequence and it flips over to PhD to start guiding, it calibrates first as expected. However, frequently it chooses a star too close to the edge of the field and then loses the star during the calibration process, at which point I will stop the calibration, choose my own guide star and resume calibration and then guiding. Then, I hop over to SGP and restart the sequence, which then works perfectly. When I go into PhD outside of this process and start it manually, it never chooses a bad guide star. Any ideas?
Thanks!

My idea would be to manually calibrate PHD2 and make sure re-calibrate when changing targets is turned off as well as any other options to calibrate PHD2.

This way SGP will ONLY select a guide star and start guiding.

Also when you change targets you should not need to re-calibrate as the current coordinates are adapted intelligently. Only if you are using a ST4 cable do you need to re-calibrate. This is what I was told anyways.
