Notices are still on some posts after claiming SE accounts and the score appears to only count votes on posts after the account was claimed

These users Cobaltduck and Oddeer both claimed their SE accounts and their posts are correctly associated.

However on some of the posts, example 1, example 2 there is still a notice saying that it was sourced from SE which is no longer needed and doesn't appear on my claimed posts.

Also, both profiles seem to have a much lower score then would be expected, what it looks like to me is that votes I cast on their posts don't count if the account had yet to be claimed. Currently, if I go upvote one of their posts it does increase their score.

(See meta post for links.)

We saw some earlier cases of after-claim attribution notices on Writing and Outdoors (maybe SciSpec too), which were reported and fixed in the DB by Art at the time. We thought those were one-off glitches at the time, and they were discovered soon after the import (as the communities were setting up), so we didn't notice any before-vs-after-claim voting effects at the time. We probably need to figure out how to check all the imports for this situation.

Problem still exists. Presumably a data error.
