Have you measured the length of the stays? I think if the nds stay is a bit longer than the ds stay it will cause your problem. If your dropouts are vertical (I can’t tell from pics), I’m not sure what can be done, maybe that is when one resorts to a file?. If the dropouts are horizontal, you should be able to adjust how far into the dropouts you pull the wheel back on each side to center things up. Only a 1mm difference in stay length can make a very noticeable difference at the rim.
