prob. with xperimental interface

I tried volumio3 xperimental interface and encounter this problem :
I use to play my CD Collection from a USB Hard drive. All CDs appear in “Albums”, I choose an artist, then click menu “Add to queue” right of the album line, nothing happens, music does not go to queue.
Menu “Replace and play” goes the same. To listen to music, i must click on menu “Add to queue” for every single track…
When i de-activate xperimental interface, everything goes right.
Is it a bug ?
