Builder error

[ams_nanolab]

Hi, while using translate tool in the builder in 2016.4, I often get this error pasted below:

Traceback (most recent call last):
  File "/home/ams/QuantumWise/VNL-ATK-2016.4/lib/python2.7/site-packages/AddOns/BuilderCore/PanelPlugins/TranslatePlugin.py", line 173, in applyClicked
    translation = _computeTranslation(configuration, self.translation(), fractional)
  File "/home/ams/QuantumWise/VNL-ATK-2016.4/lib/python2.7/site-packages/AddOns/BuilderCore/PanelPlugins/TranslatePlugin.py", line 227, in _computeTranslation
    translation = gui_translation*Angstrom
  File "./zipdir/NL/CommonConcepts/PhysicalQuantity.py", line 2001, in __mul__
NLValueError: Multiplying the unit Ang with "[None, None, -1.0]" of type <type 'list'> failed.

what is the solution to this
