Software simulation recording creates uneditable object in Captivate 8

Has anyone else had this issue? I go to create a software simulation and record my screens. I then go to add audio across several slides. I add the audio to slide 1 and Captivate 8 asks me if it should distribute over several slides. I select the option to distribute the audio and Captivate 8 opens the Audio editor. When I try to adjust the audio, Captivate 8 tells me that I am unable to shorten slide 1 at all. Slide 1 is "stuck" at the length of the imported audio file.

As far as I can tell, here is what is happening. When Captivate records the screenshot it creates the background but it also creates an uneditable object (that does not appear on the timeline or allow itself to be selected) that seems to be related to anything that has multiple states in the tool. When I go to add audio, Captivate imports the audio to the slide and then opens the editor to allow me to distribute the audio. However, the uneditable object has expanded invisibly (like a balloon in a vacuum) on the timeline to exist for the length of the slide, which Captivate has temporarily set to the length of the audio clip. When I go to edit the slide timing in the audio editor Captivate 8 says "ah, there is an object here that is set to X length, so you can't adjust the slide any shorter than the length of that object."

It's frustrating.

One workaround seems to be manually taking a screenshot every time the screen changes, but that can be a pain. Another is to copy background on the slide with the uneditable object and create a new slide without the object, however, this means that the screenshot in the new slide doesn't contain the information in the uneditable object.

Is Adobe aware of this? Are there plans for a fix? Anyone got a better workaround?
