Able to manage apps on one machine, but not another

I have a seat on my company's enterprise account. On my laptop I was able to download and update all of the apps on our plan using the creative cloud,  signed into this same account.

I am unable to do the same on my 2019 iMac. It has 2019 versions of the software already installed (maybe from a disk or download rather than the cloud) and is not listed as a registered device on my account. When I try to update or download fresh copies of any of the software, my creative cloud app says I don't have access to manage apps - but I do have access to manage them on my other machine, using the same credentials, so why won't it work on this one? 

I'm afraid to uninstall all of the old software on my desktop without being certain that I'll have the ability to replace it with a new copy. I've contacted my admin and so far they've not been able to help with my issue which is why I'm here. Since I can download software to a different machine using this account, it seems the permissions must be somewhere else. Any help is appreciated so that I can steer my IT team towards a solution.
