Firstly, does the repeating panel contain the right fields? If so, try moving the repeating panel a bit on the form. Do the fields move with it? If not then they are not really in the repeating panel. To correct this, select all the fields and cut them from the form; select the repeating panel so that the panel edges are highlighted and paste the fields into it. Try moving it again to check they are now in the repeating panel. If they still don't move, try deleting both the fields and repeating panel and setting it up from scratch.
Other things you may need to check are whether or not the data is actually there in the right database and fields, and that the database is meaningfully joined to the parent database.
