Hi, It is the way Advance Steel External lists are done.
Right click on the box, "format border".
If you try to change the text within existing box it will revert to its original text, it does not accept changes. You need to create a new box, and modify "field content" with right click.

Just to be more precise, I would like to share what I found out about the issue of not being able to update the TextBox field contents when you want to customize your headers or footers or whatever else...
If you take a carefull look to the right pane ...
You see the Tag content...with a reference to some external data...in this case it is calling for BOM,1....
Now...go to Management Tools, Table Editor and open the database stored at...
\ProgramData\Autodesk\Advance Steel 2019\INT\Steel\Data called..."AstCrtlDb"

Open up the subtable "ErrorMessages" (I wonder why Advance Steel developers had used this table to save this type of information...)...it will show...

So...%%Text(BOM, 1) is "reading" the BOM prompt with ErrorNumber 1 that corresponds to the ErrorText "Mark"...so...one way to update this label on ALL the BOM templates...and I mean ALL of them is to simply change here this label...this will affect all future BOM external lists where this text Mark is shown....if you look down this table you see some oher familiar BOM texts...
This is not however what is normally our intention...when all we want is simply to get an user list for example in our native language or instead of "Mark" just say "Piece Mark" or whatever else...
The way to do it, without needing to erase and create new TextBoxes is simply deleting the Tag content on the right pane and then change the FieldContent to what you want to use...and save it...if you keep the Tag content as it was...then next time you open it, the system looks on the database again and it writes what is there recorded...if the Tag is empty than there is nothing to look over...and the field content is kept! This way you keep the original texts as you may need to use them in the future and customize your own BOM in an easier way...
Please note that when you create a new textbox the Tag field is empty...and this is the reason why it works also...but in a more "difficult" way as you need to adjust the textbox size and format to keep the original look.
Hope this helps...
But developers...calling this Prompts....ErrorTexts is somehow a little odd!!
