After a rule is updated to a new version, the findings shown for that rule on the Rules page might be incomplete for a short time. This is expected behavior. Findings are eventually consistent, which means they reach their final state after SSPM finishes evaluating the new rule version.
How the Rules Page Displays Findings
The Rules page displays the latest version of a rule and the findings associated with that version.

Why Findings Are Temporarily Incomplete
When a rule is updated to a new version, the first evaluation against the new version runs in batches. During this initial evaluation window, the findings shown for the rule might be temporarily incomplete because SSPM is still computing the results for the latest version.
After all batches finish, the findings are fully consistent with the latest rule version.
How Long the Evaluation Takes
The evaluation time depends on the number of resources and on the load from other evaluations running at the same time. The evaluation can take from a few minutes to an hour or two.
What You Should Do
No action is required. You can check when the rule was last updated. Open the rule and review the Change Log section in the Rule Details panel.
If the rule was updated recently, wait for some time, and then review the findings again. If the findings still look incomplete after a couple of hours, open a support ticket.
