SAP issue - Tab is not highlighted in the SAP Business One Client

Issue: When using B1UP to create a new tab for a document (Sales Opportunity or Service Call for example) you will find that when you select the created tab it is not highlighted like other tabs on the window.

Solution:  This is unfortunately an SDK limitation. If there are 9 or more pane levels on a screen tabs work but visually they cant change. 
The issue is logged with SAP and they have multiple notes on the issue: 1999769 and 2302519 (Future version candidates).
