Cannot Remove Adobe Acrobat Sign From Word 365

I removed the integration using my Microsoft 365 account by going to settings, integrated apps, remove.  Seemed to go well.

But Sign still appears on the Word ribbon and as a side panel in Word.  How do I get rid of Sign from Word and Power Point?

It is not listed as a add-in when I go to File/Options/Add-ins/Com Add-ins.  The only Adobe add-in is the Acorbat PDF Maker Office Com Addin.

Sign in not listed as an installed program when I go to Control Panel/Programs and Features.

Please help me get rid of this app or add-in or whatever it is. 

Thank you.
