Length of slide duration cannot be shortened

Problem:
I create a slide and add content, I also use CC’s with text-to-speech. Moreover, I use a background music that plays until the end of the Project.
When editing the slide (e.g. changing the CC text and text-to-speech with it), at some point, the slide remains at a minimum length, and refuses to be shortened in length, even if I remove all objects.

When I create a new, blank, slide, and copy all objects from the failing slide to that new slide (one by one), then that slide will have the proper length. Is this a bug? Or am I missing something?

ActivePresenter Version: 7

OS: W10

Notes:

Hi,

We confirm that is a bug in ActivePresenter 7 when using Timeline for editing audio/video in some cases. We will fix the issue soon.
