Copy/Paste (shortcut keys) do not work in acrobat form (PDF) created in Illustrator, Acrobat Pro

Using the CTRL+C and CTRL+V shortcut keys do not work in Acrobat Pro... how does a simple functionality like this stop working in a massive corporations software that costs an absurd amount of money?

As the title states, this is a custom form created in Illustrator, with multiple pages, used as a service report for my business. So there is a lot of text formatting and copy/pasting for proper arrangement. Right clicking a selection and choosing copy and paste works, but the shortcut keys do not work... sometimes they do? (cannot reliably recreate when it does/does not work).  I've watched the clipboard and the data will appear in the clipboard for a split second and then dissapper after using the standard keybound shortcuts.  Cut (CTRL+X) works in removing the data every time, but the data is then dispersed into nothingness, and pasting into notepad, word, any other field in any other software gives, nothing.

I've played with the security settings, this is not the solution, another party in the company uses the exact same version of Acrobat, with the exact same settings (I checked every. single. one.) and the exact same document and source material to copy and paste, they have never, not once, had this problem.
