Refund Advance Pre-Qualify is wrong?

So I am doing my taxes currently and my federal refund amount was over $4,000 but the pre-qualification for the Refund Advance Lone stated I was in the $500-$999 bracket and only pre-qualify for $250 rather than the correct $2,000 according to their tier/bracket information. Will this number be corrected when IRS accepts my refund or will I only be getting the lower $250 stated until my whole refund is in?
