Strategy from Strategy Template used in Initial Population of Genetic Build crashes the Build Strategy task in Custom Project

2. The task stops after awhile with the following message.(see below)
3. Side effect is that the Random Group mentioned, becomes deallocated from the original category.
e.g. "Direction Trigger" is in category "Direction".  after error, Random Group will prompt "You have unsaved changes" when no changes had been done by user. If click save. it will get deallocated to "No Category".
