Automix is not working…pls help

I have the regular free version. I’ve used auto mix in the past (as part of the free version) but it’s not working anymore. When I click on it, it directs to a free trial and then asked me to upgrade to pro. According to the avail options, automix is not part of pro. See attached pic (as you can see, automix does not have the word pro in the upper right corner. Can you tell me what I am doing wrong?

Thank you
