I bought my Kapex 120 with the UG wings new back in 2014.
I remember adjusting both the left & right wings by a millimetre or so to get them both dialled into the blade.
As I'm right handed, I tend to use the left hand wing the most and if I recollect correctly, there is about a 7 or 8mm gap between the right hand side of the wing and thr start of the alloy saw casting.
I'm not sure why you would need to move the wings right up to the saw casting to get the measuring scale to be accurate with the blade...?
Unless, the adhesive scale has been applied way out of position...?
Can you take a picture showing your issue that may help us advise...?
Edit. I've just had a thought.....Are the UG wings the same for all the models of Kapex 120 saws...?
The latest version of the saw, I believe may be different to my 2014 model, so perhaps the way the UG wings attach may also be different and it may vary depending on the model of saw/ UG wings......Just a thought
Here is a picture of my set up showing the LH wing and a 6mm domino that wont quite drop into the gap....
