Google Play Report Unsupported API but it is in AndroidX

Question

After finding out that my old code which was using appcompat is being deprecated because they are replacing appcompat with androidx, I converted my code over to using androidx... but I'm still getting some NonSdkApiUsedViolations in my Google Play Pre-launch report, and they are IN the AndroidX code!

I thought maybe something in my layout might be triggering it, but I don't see anything that should:
