SOME Volume Automation Missing in ProTools

Can you please attach your fcpxml and tell us where to look for this including a clip name and a time code.

Hello,

Here is what we are experiencing: When audio volume is set in FCPX with keyframes included, this volume information transfers into protools without issue

However, for any clip whose volume had been adjusted up or down without the use of a keyframe in FCPX, the volume information is lost when transferred into ProTools.
(For example, if there is a backing music track that has been reduced in volume to -10dB in FCPX, when transferred into ProTools the volume information is set to 0dB.)

Is this a setting/issue in X2Pro, or is this simply a FCPX issue?
