I was not able to replicate.  The typical question in response to strange behavior is "Are you working from your local C: Drive?"

Yep, that's the problem.  It's that faint white line offset about a third of the box length.  It doesn't show in edit mode but appears in Preview.  I didn't understand your post "It's not hard to recreate" though.

Well for previous post - it was a grphic - I was showing that she could just redraw it.  I am assuming you are using the Caption Option.  Any you are working from your C: Drive??

I would check and see if there is a state that might be creating it. I think the simplest way to fix it is to check your timeline.  See if you can find a strange box listed and remove it. Or just remove the bubble and see if it goes away. Then recreate the bubble. 

I have checked the timeline and states.  There is no phantom text box lurking in the timeline.  The only state is "normal" and no phantom shows there.

I am working from a Sharepoint drive.  Yes, I'm using the caption option.  Removing the caption and inserting a new one doesn't correct the problem.  I have it on multiple slides anywhere I'm using a caption bubble

I highly recommend that you do not work from a sharepoint drive.  You need to be working from a local C: drive

Julia it's hard to give you any help on this without the .story file to look at. If it is a confidently issue. You can make a copy and delete all the other slides and let us look at that one. If this is a corrupted file because you are work off a Sharepoint drive, you might be able to fix it. Here is what I have done in the past. Make a copy and put it on your C:drive. Then start a new project and Import your copy into the new project. Save it on your C:drvie. The see if the faint outline goes away. 

Good luck and let me know if I can help 

Thank you!  I will give the non-sharepoint option a try.

If I select the speech bubble and remove the border from the format menu the phantom offset outline disappears. Even when I don't see an issue on the "build plate" the preview doesn't have the phantom outline anymore. To be fair I do have some speech bubbles with outlines that are dark and thicker, but it seems only the thin outlines produce a light line phantom. I am planning to do more research.
