How can I get rid of stray lines in the cross sections at template transitions?

Question

I am trying to use 2 templates in my geopak SS3 corridor. When I insert my second template, I see stray lines in my dynamic cross sections. These may be related to the transition between the two templates, but I am trying to insert my second template without a transition. I don't know how to control if and how the templates connect as there doesn't seem to be a transition inserted anywhere when I review my Corridor Objects. 
 Are there any tutorials about template transitions in SS3? 
 (Power GEOAPK V8i, Version 08.11.09.722) 
 
 In this figure I have only a single template drop

This figure is the same station as above, but after I have inserted a second template drop 1ft beyond this station. I indicated 0 minimum transition distance.

This appears to just be a graphical issue. This only happens in the dynamic cross sections which are not used for any component quantities reports. If you 'Create Cross Sections' or review the 3D components in the model you do not see these stray lines. 
 I ran a test using the Corridor Modeling > Component Quantities report and at the station in question, it is reporting the station 11+500 twice but only because you have the stop template drop at 11+500 and the start of the next template at 11+500. You can see from the attached screenshot that the Volume for the second instance of the drop is not computed so there is no issue in what is reported. Also if you compare the different component volumes of that station to a previous station with the same component, the volumes of these components match so there is no change in the quantities. The closed 'area' of the shapes is not changing so the volume will be reported the same.

please check that the point names are the same on both template drops. if they are not, the program will try to connect them.

yes, that is correct.

Upon further testing, we were able to reproduce the problem and this is some bug in the program. As an initial test, I changed the design stage assigned to the corridor to the "3-Final" design stage delivered in the example workspace and the issue went away. We found that the ultimate cause of the problem is a template interval greater than 1 will cause the stray graphics to appear. So as a work around, you can either: 
 
1. Assign the design stage on the corridor as "3-Final", "4-Final W/ Meshes", or "8-Final Components" 
2. Edit your design stage that is assigned to the corridor and change the Drop Interval to 1. 
 
I will log the defect and post the defect information here for reference.
