Invoice Store Name and Address not showing

[Guest]

When I check my invoices, the Store Name, Address etc., is not shown in Bold on top of the invoice. I wonder whether anyone has the same problem. I can enter the invoice and print over, but why not have the whole thing done in software.

In case anyone ask, I have updated My Store with all my details, etc.

I simply will like to know where the BOLD Store Name, Address, Country, Phone on top of the invoice is situated in the relevant xxx.php file so that I can add the changes, if possible, because I've tried all other methods. All files in Configuration and elsewhere have been updated, and all other aspects of the program appears to function ok.
