Using AI Voices within RISE

Hi Articulate Community

I have a question regarding the AI voice generator.

Below are two examples of possible AI voices that i can choose from within the RISE AI library.

When hovering over the calendar (indicated by the red arrow) it states 'if the author removes this voice, it will remain within the module for 2 years from the date of its deletion.' However there is no date in the right hand side.

Does anyone know what no date mean with relation to author removal and possible deletion?

Thanks all

Stuart
