Audio is corrupted after editing text-to-speech

Hello. This problem happens to me all the time on large and small projects. I have the latest version of 360, save my files, etc. It has been a constant thing for over a year. It is frustrating and time consuming.

Here's what happens... after one or two edits to the Text to Speech item in the edit window, the audio item on the timeline fades out/grays out, and will not play sound no matter what I try. 

The workaround:

1. Hover over the Text to Speech item on the Timeline, then, right click and select Text to Speech to open the Edit window

2. COPY your original text (close the edit window)

3, Create a NEW text to speech item by going to Insert > Audio > Text to Speech, then PASTE your original text in the new TTP edit window

4. Select Insert (SAVE)

5. Then click on the old (audio) item on the timeline and delete it.  

I realize this adds steps, but it is better than completely losing your text... particularly when you have worked so hard tweaking the sound.

If there is a way to prevent this problem, I'm listening!

Thanks.
