Strange trigger manifestation

Hi, I'm working on a software simulation. Because of the size of the files, I created the Try mode and Test mode in two separate projects. For the final file, I imported both projects into a new project.

I've noticed that in all of the Text Entry interactions in the Try mode slides, a second trigger to "Set unassigned equal to a value when the control loses focus" has appeared that wasn't in the original file. I am unable to delete this trigger (that option is disabled), and I'm hesitant to assign the text entry variable to this duplicate trigger. I've checked the Form view of the slide to see if another text entry option became available, and everything looks ok.

I've taken one of the slides from the project and am attaching it below. Has anyone seen this before? Is there a way to remove the second text entry trigger? The second trigger doesn't seem to be creating any problems with the interaction, so would it be a problem to leave it?

Thanks,
