Try removing the colon ":" from the name of the locks that include them.

Device Name vs Device Label in Drivers

Nope, free to name them how you see fit. Good note though, try to avoid special characters and you will avoid special results... Special characters typically are: % $ : , . # < > / \ { } [ ] @ ` ' " We do what we can to trap for these but highly recommend you don't use them in labels and names of devices.
