Context menu process loading issue

Hello
We have Time Phase Inquiry Form. There is one Base Extension in it and below that base extension we have Customization. It contain one additional tab and some of information on it.

We have modified menu items by setting that customization in each of them. When we are opening form from the menu everything works fine.

We also use this menu item as a Process ID under Columns Like Part.PartNum in the Context Menu Maintenance.
The problem is when we are opening this customized form from context menu. The form is not showing that additional tab we added.

After it opens we go to the Tools → Customization and we can see the tab is there. After we click on it in the tree view and after that click on the standard tab also in the tree view our tab appears on the form itself.

One more thing is that when we go for Tools → Reset Layouts To Base then the tab magically appears.

I have tried to do some scripting tricks like focusing, showing tabs on different form events but it did not help.

There must be a difference between the way of form loading normally from the menu and by the Open With context menu.

If someone has faced that kind of problems please join the discussion.
