The two alert cards are built by checking each area of the vessel separately. An empty card is a claim about all of them at once, so the page is careful never to make that claim until every check has come back.
While the checks are running
Just after the page opens, a card with nothing in it yet shows Checking for alerts…. Rows appear as each area reports in. The all-clear message is held back until they have all answered.
When a check fails
If an area cannot be reached, a yellow notice appears at the top of the page naming it — for example Couldn't check Crew Documents or Couldn't check Controlled Documents. It warns that anything outstanding there is missing from the list below, so what you are looking at is not an all-clear.
The notice carries a Retry button, which re-runs every check at once; reloading the page has the same effect. Once all of them answer, the notice disappears.
The notice is shown once for the whole page — above the cards, or above the tabs on a phone — rather than inside each card, so a single failure is reported once even though both cards are short of rows because of it.
The all-clear
Rest assured, there are currently no concerns to address. appears only when every check that was meant to run has returned and none of them found anything.
Areas that were skipped are not failures and do not hold anything back. An area is skipped when the yacht is not licensed for that module, when your role or permissions have nothing to report there (for example, work and rest hours are only checked for captains and crew, and risk assessments only for users who can edit them), or when the feature is not available in the app you are using — the on-board app does not check crew documents, crew forms, controlled documents, work and rest hours, or risk assessments. Those areas simply are not part of your list.
Notifications are separate
This only concerns the alert cards. The notifications feed loads on its own and is unaffected by an area failing to report.
