are these stitch errors acceptable?

My lens is set at NPP (I hope), with R1 using the rotator setup on a tripod. Equip is sigma 8mm f3.5 with 5d mk2

PTgui align with auto control points.

I still get a minor problems shown in the img:

I think that as I have set all perfectly I should not be getting any errors.

right? What I'm missing?

Can you provide a set of image for others to stitch them?

Hi,
you have some stitching errors in the lower picture on the boxes.

What is the setting you used on the R1?

Send pics if you like, I'll try to give some help.
