Fixes duplicate alert icon in storage banner

What does this MR do and why?

Fixes duplicate alert icon in storage banner

No changelog as this banner is behind multiple disabled feature flags

Screenshots or screen recordings

Screenshots are required for UI changes, and strongly recommended for all other merge requests.
