The problem you’re experiencing is sort of a “known issue” with the way SharePoint operates. Basically, when you access items through a Web Part, the system doesn’t understand where you’re accessing it from, so the link to the list isn’t known. Therefore, it breaks the status link.
There’s nothing Nintex can really do about it since this is default SharePoint behaviour. But you’re a Nintex customer, and I want you to be able to work – so we may have a workaround for you:
1. On the List where the WorkFlow is running, add an additional Hyperlink Field
2. Within WorkFlow Designer, insert an update item action
3. Have the action update the Hyperlink Field with a reference to the WorkFlow Status (screenshot attached)
Now, when you're executing the WorkFlow, click the update link to view the current status.
We use a very similar workaround internally, from time to time. I hope this helps!
