Context Menu Error with Ravalox

[Dynacel]

Any time I attempt to use a drop-down menu, regardless of which menu, I get this error:

EsoUI/Libraries/ZO_ContextMenus/ZO_ContextMenus.lua:278: attempt to index a nil value
stack traceback:
EsoUI/Libraries/ZO_ContextMenus/ZO_ContextMenus.lua:278: in function 'AddMenuItem'

Disabling Ravalox Quest Tracker resolves the issue, but I'd like to use the quest tracker. I'm currently using version 3.5.0.0 of Ravalox.
