How to get back a tab name that disappeared

[jjjjp]

I was adding files to a tab, which is very hard if you haven't worked with tabs in some time. Hard to select exactly what you want to.

Somehow one of the tab names disappeared. The name for the fourth tab should be send.

 

 

I can't see how to recover it in the tabs setup:

 

 

As you can see, the same appears correctly in Tab Control Setup.

How to get it to reappear?

Thanks.

What happens if you copy the tab control object and paste it into a brand new file?

If the label is still missing, please post the (new) file.

That didn't seem to work. I assume you meant paste it into a brand new layout, but I also tried pasting it into a new file.

What ended up working was creating a new tab of the same name and pasting the contents of the label-less panel into a new blank panel with the desired name. Then I deleted the problem panel and moved the new one to the correct position. 

 

Thanks.
