PeopleSoft Test Framework + Page.Prompt not switching to add mode

Hi,

I have a PTF test step as shown below. In this step I am try to navigate to the page and switching  the mode to Add. It is working fine on my machine (64 bit, Windows 2008, IE 11)

However, when my colleague tries to execute the script (64 bit, Win 10, IE 11), the step does not switch to Add mode. So I had to add an extra step to force it to move to Add screen by clicking on the 'Add a new Value' tab link.

Extra step added for my colleague:

The id: ICTAB_1 is the id for the 'Add a New Value tab'
