Justin, since you didn't mention hinky extraction as an issue to begin with, I'd put the original extractor spring back into it. I'm sure you cleaned out its well and gave it a drop of oil when changing before...

I recall a thread here not to long ago discussing an ejector that was misbehaving, and IIRC, the final solution was to dress the front edge of the ejector's tab. Apparently, if the edge is angled back when the action is rearmost, the edge will hit the shell on the lower right instead of the bottom the rim. Straight up ejection is unimpeded, as designed. Ejection angled off to the left side, not so much. In the case of that other gun, I think it was denting cases. But I'd say that any situation that misdirects or impedes the ejecting shell's travel can also mess up ejection.

Since the ejector is a replacement, it's worth a look.
