Advanced actions work on one slide and don't work on another

Hi,

In a slide I have split a fluid box in two columns. The left column is split in three rows where I placed three buttons. The right column is split in two rows. In the first row I have placed a multi-state text caption and in the second row a multi-state video. When the user clicks on the first button, the state of the text caption and the video changes from normal to its first state and so on.

I have done this in two slides and it works only in one of them. I have double and triple checked the advanced actions and variables and everything you may think of. The two slides are identical from this point of view. Unfortunately, in the first slide only the video appears but not the text. Any idea why does this happen? I use Captivate 2017.

Thank you for your time.
