Why is my app name getting numbers added in its URL on Shopify?

Hello,

We are trying to get our app up on Shopify and noticed our app name is getting a “-1” (or “-3”) appended to it. Why is this and how do we correct it? Our company name is a registered trademark and we want the url to just be our trademark, “Handwrytten” and not “Handwrytten-3”.

Thank you in advance!
