Global Variable returning Value as Null in 5.6.3 Katalon studio

I am facing error Global Variable returning Value as Null
I have created a new profile named as “DEMO”

Though I use the profile “DEMO” while executing the script as shown in below screenshot
I am still facing below error
[ERROR] - Test Cases/TC02_HotelBooking_E2E_InputDataFromExcel FAILED because (of) java.lang.NullPointerException: Cannot execute null+{HotelURL=, Screenshotpath=C:\Katalon Studio\AdactinDemo\, Username=xxxx, UserPwd=xxxxx}

My script worked fine till 5.5 version of KatalonStudio,** I am facing this issue on 5.6.3 Katalon Studio**
