Development Environment - Duplicate Checkbox Issue

In our development Docusign environment, we are seeing duplicate control fills -

 

We do not see this in production Docusign and cannot trace this to code related or template related issues.  Is anyone seeing this in their Docusign development environment?  The only other thing we could think of is that the base pdf is somehow filling an underlying pdf control….but this started occurring in all of our templates simultaneously, even ones we have not touched in some time.
