Cant change user labels for pins in cube 6.6.1

[jhanc.11]

I tried to change the user label for multiple pins in Cube 6.6.1 running on a mac without luck. On the rare occasion where it takes the label, it ends up on the pin in the table reversed and you can't change it. For instance, I entered "TIM3" and it resolved in the table to 3MIT.

Thanks
