My hotkeys got messed up somehow

While doing Tam-tara Deepcroft, about midway through the dungeon my hotkeys did something weird.

They literally connected themselves together, so now I have 2 hotkeys that show the exact same info, only let me use the same exact skills, and attempted to change one also changes the other.

I have absolutely no clue what happened. Here's a screenshot of basically the issue:

In the screenshots, I removed Sustain from the leftmost bar, and it removed it from the right bar as well.

I've tried changing between HUD sets, but the issue persists regardless of which HUD preset I choose, and disabling and reenabling Hotkey Set 1 does not fix it either. (It still hides it like it should, but doesn't stop it from being COMPLETELY connected to Hotkey Set 2)

Platform: PC

EDIT: I fixed it. Apparently, I accidentally hit "Shift+v", which caused my first hotkey set to cycle downward. I'm going to leave this up here for other people in case they screw this up like I did.

If you are not of a playstyle that specifically and deliberately uses keybinds to switch hotbars, it's helpful to disable those keybinds outright.

/keybind
System tab

Clear all the following keybinds:

• Cycle through Hotbars(Up)
• Cycle through Hotbars (Down)
• Switch to Hotbar 1
• Switch to Hotbar 2
• Switch to Hotbar 3
• Switch to Hotbar 4
• Switch to Hotbar 5
• Switch to Hotbar 6
• Switch to Hotbar 7
• Switch to Hotbar 8
• Switch to Hotbar 9
• Switch to Hotbar 10
• Switch to Pet Hotbar

That's a good idea I never considered. Thank you!

Fwiw there is an option somewhere to disable cycling hotbars. I forget where exactly, and can't check atm since im not at home. I have it set since there's nothing worse than having it happen in the middle of a fight and scrambling to figure out what went wrong and how to fix it.

Edit: I'm home now and found exactly where the setting is for you:
Character Configuration (K) --> Hotbar settings --> Display (this is the default tab) --> "Enable hotbar cycling button"

Although, from testing it doesn't appear to prevent the keybinds from working. Just removes the clickable button to the left of the hotbar.

Thanks, I had the hotbar cycling buttons and keybinds removed, but not all the Switch-To ones. Hopefully disabling them will stop the unwanted cycling.

Edit: It did. All my pars stay put, unless I forget to re-lock the buttons.
