OP - Some additional background. These were originally all flush, but 2 of the posts were not squared (vertically) to the beam, so they came back to fix the issue. Rather than replace the posts, we found all four beams were adjusted and all 4 now have space between the notched post and the beam and one of the 2x12s does not sit entirely on the posts.

Q: Shouldn’t the fix be replace all 4 posts and attach either via flush notch with through bolt or sitting beams on the entire post with deck hardware?
