Screen readers and different text in text states?

I am working a government contract that is 508 compliance mandatory and the screen reader will not recognize the text boxes in my project. They appear in the Focus Order and I have even applied alt text to my text boxes to no avail. Is there a setting that I am missing.

I updated Storyline 360 on 5 Apr 2021.

 I right click on my text box and select accessibility. I select Object is visible to accessibility tools. I enter in my alt text. and I close. I then select Focus Order and ensure that my text box is present and the alt text is present. I then publish it for the web for my 508 compliance team to test.

I also open the file on Microsoft Edge and tab through the project. The text boxes are not tab able and I keep failing 508 compliance standards because of the text boxes not being read.

Any help you would be greatly appreciated.
