End date is greyed out while raising the travel plan

Dear Team,

I am facing an issue with Raising a travel request in the portal.

The end date is greyed out and when ever employee is filling out Start date of the trip, system automatically taking that as end date of the trip.

As per the requirement, Employee has to go fillout the End date of the trip.

Could you please advice me to enable the End date field.

Regards,

Sairam.
