Question - Cross Hotbar "Hide but Active" Option?

[Niwashi]

Crossbar 3 still shows up when I switch between crossbar 1 and 2 by pressing just R1.

There are actually two lists, one for which to cycle between with R1 when your weapon is drawn, and another for which to cycle between when your weapon is sheathed. Did you set it only for one way and then test it with the other? It generally works best if you check both of the "Enable customization when ..." boxes. If you want to use the same hotbars in each case, just have the selections in both sections match. But it also lets you separate them if you want - like I have mine cycle between bars 1 and 2 in combat (or any time I draw my weapon), but stay on bar 3 when my weapon is sheathed (then I have bar 4 as my extended crossbar and 8 as my W crossbar).

The other thing that could account for it not seeming to work is that the whole "Custom" tab of the Hotbar Settings page has an upper half for PvE settings and a lower half for PvP settings (though that whole lower half is optional and can be enabled or disabled). Be sure you're setting it in the right section.
