Acrobat Pro DC toolbars not staying session to session

We have a client whom just purchased the portal licensed version of Adobe Acrobat DC Standard. We tried it on her system before rolling it out, and it's a good thing we did, as now her toolbars are being erased when she opens up other documents. They use PDFlyer and I found others with similar issues.

Users should be able to customize their toolbars without having them wiped out depending on if they open a document from Outlook, from the web, or from the program itself.  Has there been a solution posted? She is logged in under her account with the latest version.

OS: Windows 7/10

Version: Adobe Acrobat DC Standard

We're holding off on rolling out and may even ask for a refund if this has now become an Adobe "feature".

Thanks!
