Hi @Christopher64 and welcome.
I don't know what your minimum is, but it looks like the price at the top is your nightly price after a 20% discount. When I go to your listing, I see that it's $45 a night, and below that there's the 20% discount offer:
When I put in dates, the price changes to $51, but in the nightly breakdown, it's $63. $51 is 80% of $63, so the price they're showing is your price less the discount:
If you need to bring in more than the discounted price shown here, raise your minimum to cover yourself. And I don't know if you know this, but new listings get a boost in the search results and rankings, so you don't really need to offer a discount at the beginning.
