Dials ALT text?

Hello Community!

We are building some accessible interactions - and one of them uses dials to open a padlock. 

In our QA testing - no matter what we add in the alt text for the dial, the screen reader adds on the name of the object and range 0 -12.

Is this a default? Has anyone else come across this?

Any ideas on how to remove it?
