Kit assignments (driver and equipment)

Hello,

For OTM 6.3.2. we've found the following Kit Assignment Enhancement:

Kit is defined as the relationship between driver, power unit and equipment.

For kit assignments, the previously existing requirements for location asset inventory are relaxed. There is no longer a need to set up and maintain location asset inventory buckets and bucket values if kits are all that are being assigned.

There is instruction for setup (attached). But after completing all this steps we still get the exception when run Assign Driver action ->  Show Options. OTM shows correct list of drivers, but when we choose driver we get the java.lang.NullPointerException.
