Warnings result of the date filter validation if any.
When loading a date filter configuration, it can have some issues that we surface (e.g. having zero visible items). These are not blocking though, if any issue is encountered, the config falls back to something sane. The reason for storing this here is mainly for us to be able to show a warning when some issues are detected.
