Why are submissions showing up twice?

Our forms go to specific people depending on the contents, and we're all getting the appropriate submissions, but we're getting them each twice. I took a look at the settings, and nothing seems to be amiss.

You have the same email action for more than 1 conditions, that's why you're getting multiple emails.

Take this for example:

If you are conditionally sending the same notification to the same email address, consolidate them instead into a single condition, such as this:

Apply the same principle to all the conditions and your problem should be resolved.

Cheers!
