Subject: [PATCH] Add undefined fallback for valueMonth state
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Added else clauses to set valueMonth to undefined when month values are not provided:
- Prevents stale date values in calendar
- Ensures calendar displays correctly when switching between date ranges
