For knives where the spine is thicker than about 2-3 mm, the center axis of the knife blade is not in line with the center axis of the SVM-45 jig shaft, resulting in asymmetric bevels.
How do you avoid this? (I don't want to have to reset the angle for each side of the knife.)
I have been battling this issue, especially with Japanese single bevel (concave back) knives.
I have had some moderate success using small popsicle sticks under the leading edge of the jig.
A PIA to clamp, but seems to work well.
Multiple layers of tape and or washers (shims) also work.

One option (that I haven't done myself) is to thin the inside of the jig, described here:

A forum member posted this solution (also haven't tried)...

Schleifjunkies sells a "self centering" jig (his website is currently down, but should be back in a few days)...

I'lve had success using a Lansky jig that "self centers"....

... I've also used a KME jig, seen in this post...

Probably works for your example, but you can't shim a blade that is too thick for the SVM-45... it's already off center and a shim makes it worse.
My shop was down for 3 Day`s due to Inventory.
here ist the Link to the Clamp:
