Automatic update for Acrobat Reader DC does not update

I have a computer lab all installed with Acrobat Reader DC. Some of them are on  version 2019.008.20071, and some are on 2019.008.20074. We are having an issue with the header being cut off / trimmed when printing in Acrobat Reader version 2019.008.20071, but prints perfectly fine in version 2019.008.20074. Why is it that some PCs are able to update automatically, and others are not? How can I trigger the automatic update for all the PCs, and not have to manually update each computer 1 by 1? All PCs have the AdobeARMservice started.
