When using the shortcut to paste attributes copied from another clip, the beta will paste a copy of the copied clip, rather than the attributes of that clip to the new clip.
I did a lot of keyboard customization, ALT+R was my combination for paste attributes, I never used a default keyboard and I didn't know the default one. I just assigned another combination ( CTLR+ALT+R ) to paste attributes now, I'm using that without any problems.
