Startrails with star adventurer 2i

[AstroNebulee]

 Hi

I managed to get first light with my star adventurer 2i last night but was getting startrsils at even 55mm with my dslr, I could go 2 mins at 18mm with none but higher led to star trails. I set up in this way. Place tripod mount facing north, put the dec bracket and dslr on. Then level the tripod using the bubblesl level on the wedge to be dead centre. Changed the alt wedge to my lattitude and I saw polaris my polar scope. The polar scope was set to 0 at the top and 6 at the bottom. I opened the Sam console app to find where to place polaris in the clock and succeed in this and polaris looked like it was tracking all around the clock when turning the RA. So thought all was good. But was getting star trails at anything around 55mm and over at 1min or lower subs. I believe I balanced the dslr in the dec bracket successfully (I wanted to use the dec bracket so I could keep checking that polaris was still following the correct path by looking through the hole in the bracket). Previous to this I calibrated the polar scope and you can see on the attached gif file that it stays on point. So not sure what was causing my star trails. So could someone check my polar scope is calibrated correctly. I'll attach the individual images of its easier. Any help kindly appreciated.
