Constraints and Values in the Form Designer in VRA

Hi All,

I am creating a custom resource action form for ADD new disk. I would like to use a same form for Windows and Linux so I used Constraints features to show form fields based on Gust OS. but the fields and not visible after adding the condition.

vm > Guest OS > equals > windows

vm > Guest OS > contains > windows

Expected : The drop down should visible for windows as per above conditions.

Actual :  The dropdown is not visible for windows vm.

Please refer the attachment.

Thanks in Advance.
