Cannot clear/move/Remove default hotbars AGAIN!!!!

[Strider24]

Hello. Im new to LOTRO, I have much exp with other MMOs.. My problem is that I cannot equip abillities into the upper hotbar (I have the Hunter UI) they seem to overlap with the default UI aux hotbars. Is there a way to move or remove those default hotbars so I can just use the 2 suppled by the UI mod?
Well It's the same problem as Halafax!
When I download a new skin and are about to pull my extra skills over an empty slot in the more laugher skin it just jumps out of my regualer skin slots, as if there wasen't any new slots avaible?!?! And I think it sucks that you have to push shift or control buttons to have the extra skills you have purchased showed, when you are in a fight!!!!
Please, please, please someone help me
