Add the raising promotional codes on the website (on the website of the promotion code)

The project skidkov.ru. The website with the promo codes. On Wordpress.
The problem is that the list of promo codes on the stores page itself is changing ( with priority to high. For example, one put a priority of 1, the second 2, etc (or wherever you put unity, they are all upstairs). Me 5 pieces high you need to raise. Where is the priority there, it is there itself as it is now.
