"Dark Box Text Lower Third" title problem

Hello,
I have a small problem with one of the fusion titles. Here's a screencast:

I have seen this happen only to the "Dark Box Text Lower Third" fusion title.
When copying one of those clips (either via alt+dragging, ctrl+c/ctrl+v or by dragging them in and out of the media window) the little line on the left disappears. When resetting the clip the line reappears, but of course all settings get lost.
It also happens at seemingly random moments, which is especially annoying when you notice it only in the final render (since in the viewport the clip might be cached and actually show the line).
Does this only happen to me? If not, does anyone know of a workaround?
