Import/Save As TWS Projects

Hello,

I found a problem, when I try to create a copy of my projects for showing new models.

When I make copy of a project via Save As or Export/Import, project look correctly in preview:

but in ThingWorx View (in device) does not load any resources (images/model):

Has someone the same promblem or a solution  ?

Thank you for each reaction.

Regard

Tomas
