Number of Days automatically getting picked when creating Expense Report

Content

Hi Experts,

I am facing an issue, I have an employee for whom when I try to create a Expense Report, the Number of Days field is automatically capturing the value 50, and when I try to edit it as 1, I an getting am error as you can see in the below screen shot.

Can anyone help me to understand why the system is behaving like this.

Thank you in advance.

 

Best,
