Hey all,
I'm a first time poster here and I've only just recently begun learning how to use Power Apps, so I do understand that this question may be a bit basic.
I'm having the hardest time trying to edit each text input individually on this field map. I've posted a screenshot below.

As an example, I'd like to edit the text inputs a little bit. For instance, 'amountdue' would be 'Amount Due' and 'shippingAddress' would be 'Shipping Address.' Power Apps is only allowing me to edit the first text input (amountdue), but is not giving me the ability to edit the other text inputs individually. It's almost as if everything is 'locked,' so to speak. As far as my limited training has shown, I should be able to easily edit the text inputs individually? Though, now I'm wondering if this may have to do with the fact that this is a Field Map.
Is it possible to edit these text inputs individually? If so, what am I doing wrong and how can I go about this?
I don't know if this is relevant at all, but this is a Document Automation Application that was taken from Power Automate (in other words, I did not create this app from the ground up).
Thanks!
