The collects on the 2nd floor are on the floor at or near the wall. As you approach the collect, the collect sinks into the floor. Attempting to pick any of them up is fruitless. I could not find any display option that could remedy this. FWIW, I play on the Tunare server (if that matters).
While in some zones in TOV I had to unselect Options/Display/Advanced/Allow 2.0 Shaders to see the collects (the moving ice obscured your view), it is the opposite on the 2nd Floor of COV Skyshrine. Once I enabled Allow 2.0 Shaders I was able to see the location of the collects as I got closer.
