Check boxes not transmitting on docusigned pdfs

Hello:

When using Docusign for my business, a client will e-sign a perfectly completed PDF form with the exact processing instructions. When I go to trnasmit the form to a provider, the checked boxes aren't showing up even though everything is in good order on the saved version. I normally submit using Ring Central Fax or will upload directly to the providers site. For example, American Funds.

Whats up with this? Is it a setting that's off?
