Hello garyc0424,
Thanks for reaching out to Apple Support Communities. Upon review of your post, it seems that you have a duplicate app on your iPad that you cannot get rid of. We can see why you’d want this taken care of, so let us help from here! Let’s start by explaining that the best way to remove that app is simply to delete it, which can refresh the settings and help the iPad recognize the duplicate. That is explained here: Remove apps from iPad.
We understand that you don’t wish to lose data on the app, which is completely understandable. You did not mention which app it is, so we can’t give specifics here, but you may wish to back up your device first (explained here: Back up iPad) or check with the app manufacturer to find out how to secure your data first.
Please let us know if you have follow up questions, so we can continue assisting. Take care!
