Change name of primary button from "Next" to "Submit"

We have had the same issue, and our solution to this is that we have two constants for the button's label and value.

Constant for button label: "Submit "
Constant for button value: "Submit"

By putting a space in the label will prevent Appian from renaming it to Next.

For more details, go to forum.appian.com/.../Button_Field_Input
In the documentation, this might be what you want to read:

If you do not modify the Label value and the form is for an attended node that is activity-chained to the next node in the process model, the label will display to users as Continue on Tempo forms and Next on legacy forms.

Hope it helps.
