3816026 - Why does several expense types appear in two or more line items show different cost centers?

I want to confirm the cost centers are mapped to different expense types. While looking at her AP/GL Extract, she noticed that several expense types show twice and mapped to different cost centers. 

Example: 
User Name 1
Expense Type : Business Meals 
$99.53 
Cost Centers: 
609238 
609117
