Katalyst: Incorrect default language or locale (number/date format)

Description

• Users see UI labels, date formats, and decimal separators that do not match their locale:
  • For example, MM/DD/YYYY vs DD/MM/YYYY, or 1,234.56 vs 1.234,56.
• In mixed‑region deployments this can cause confusion when reading dates or numeric values.

Solution

• Confirm environment locale configuration:
  • Check server‑side locale or Katalyst configuration for default language and region.
  • Confirm database and OS regional settings are consistent with desired defaults.
• Client/user configuration:
  • If Katalyst supports user‑specific preferences for language/region, ensure each user has the correct settings.
  • Consider browser or OS locale settings if the UI respects those.
• Standardization:
  • For multi‑region deployments, agree on:
    • A default system locale (e.g., English + ISO date formats).
    • Whether user overrides are allowed.
