No Previous Button in Agentry Loop over collection screens

Hi Team,

We are not able to find the Previous buttons in Agentry Loop Over collection Transaction screens in Work Manager 6.2. But in the Wizard buttons I can see it is enabled.

See attachment.

But it is not displayed in iPad or even in windows client.

Experts please help me to find out what I am missing to enable the previous button.

Help is much appreciated.

Thanks,

Bala
