High vibration in Cube Orange+

I just got an X4 from UAV Systems International. It came with arudcopter loaded on a Cube Orange+, but i switched over to PX4 and did a few test flights. The Cube Orange+ is hard mounted, but I though that was okay for the cube since 2 of the imus are mechanically isolated. My drone was a bit twitchy during the flights so I checked the accel logs and sure enough I’m seeing big vibration. Plots are attatched. What is weird is that the first 2 imus are high, but I thought they’d be lower. Any idea what is going on here? I’m at a loss. I could do some vibe isolation but that shouldn’t be needed here. I’m more concerned and the two imus showing high accel that the third.

Thanks in advance.
