The Double the Donation add-on should only display their form field once on guest-donations-disabled forms.

Currently, if a form has guest donations disabled in the individual form settings, and either the "registration", "login" or "registration and login" option selected, the GiveWP Double The Donation add-on displays twice.
This happens on all three form templates.
Also, this happens only if you access the website while you are logged out OR using an incognito tab.

Our team will have a look at this.
Issues like this that are not preventing donations or have a simple workaround are generally prioritized at the end of an 8 week development cycle, and then tested and released. That means it can be up to 10 weeks for issues like this to be resolved.
