Guiding query

I have a query about my guiding behaviour. When I start an image, my guiding graph start off with the Dec (red line) moving a lot for a few seconds, then it corrects and starts guiding quite happily. I have attached a screenshot showing this. The second shot shows a reasonable graph a while later. Both of these are during an imaging run of Eta Carina.
Gear used is

Mount Orion Atlas AZ/EQ G
Guidescope Orion ST80
Guide camera Orion SSAG Pro ( I believe this is a rebadged QHY5?)
Guiding with PHD 2 version 2.6

It almost feels like despite calibrating, it wants to check it again and moves whe mount a bit more before settling down. The images in the main scope appear OK. It is just annoying that it seems to happen each time.
