To fact-check your claim, I looked at your source and compared it to another. I was able to verify that this registration error was in fact due to Oregon's 2016 motor voter law, which automatically registers people who obtain new driver's licenses. Those who do not have citizenship and were registered was due to an operator error: "The state now says that a poorly laid out dropdown menu in a DMV computer program led workers to mistakenly indicate that noncitizens had presented U.S. passports or birth certificates when they had not." VanderHart, D. (2024, 9, 23). Updated findings show nearly 1,260 possible noncitizens were registered to vote in Oregon since 2021.

The article says that 10 of those people who were improperly registered went on to vote, although at least one person had become a U.S. citizen by the time they cast their ballot. The director of the Oregon Department of Transportation told reporters that agencies "have continued to implement swift corrective action to ensure that this data processing error will not impact the 2024 election or future elections." The article clarifies that corrective actions have been taken, such as revising the dropdown menu and requiring DMW workers enter an applicant's state of birth, and that office managers review transactions to make sure entries are correct.
Governor Kotek was quoted in the article and mentioned providing updated staff training, and completing a "comprehensive after action report," in addition to launching an external review of the DMV's data by the end of the year.
In summary, it appear that this claim was correct, but action has and is continuing to be taken to ensure mistakes like these will not happen in the future.
