How can show the symbol Table or Define name in Name Manager dialog box?

[T_Anirut]

I am setting the Table name and check in Name Manage and cannot find the symbol that usually will show in front of Name. You can see as attached file.

Could you please advise me how can fix this one. 

PS.  I use Excel 365 version.

Is it possible for you to attach a copy of the Excel spreadsheet involved here, and maybe give a more complete description of what you're attempting to do as well as what's happening?
