How to change the gear from Dante? (Devil May Cry 5)

In one of the tabs swords completely removed everything except the sword of Dante, click on an empty cell and can't add weapons slots to select, no mouse, no buttons don't allow to select the bottom cell, just swap with the neighboring cells. In other tabs also can change weapons in some places and removed from the cells, and add no.

Similarly, with the trunks, unlocked dual Kalina Ann, when you select a menu below offers the possibility to svinetice on a single, but fails.

There is a decision problem?
