Confusion between (FORM ...) and (p FORM <NAME> <NOINSERT>)

In this template I prompt for the date using org-mode. This example will prompt me twice. But if I use (p FORM ...)

(intro_movil
 "*** Tarea"
 n ":PROPERTIES:"
 n ":EXPORT_LATEX_CLASS_OPTIONS: [11pt]"
 n ":EXPORT_TITLE: *" (s title) "*"
 n ":EXPORT_LATEX_HEADER: \\usepackage{titling}"
 n ":EXPORT_LATEX_HEADER+: \\preauthor{\\begin{center}\\includegraphics[width=.4\\textwidth]{~/Dropbox (Maestral)/org/attachments/ITLA_LOGO.png}}"
 n ":EXPORT_LATEX_HEADER+: \\postauthor{\\end{center}}"
 n ":EXPORT_FILE_NAME: " title " - Amadis Genao Suarez - Introducción al desarrollo de aplicaciones móviles"
 n ":EXPORT_AUTHOR: "
 "$\\\\$ Nombre: $\\\\$ Frairlyn Camilo Roque Suarez "
 "$\\\\[0.1in]$ Docente: $\\\\$ Amadis Genao Suarez "
 "$\\\\[0.1in]$ Matricula: $\\\\$ 2023-0295 "
 "$\\\\[0.1in]$ Asignatura: $\\\\$ Introducción al desarrollo de aplicaciones móviles "
 "$\\\\[0.1in]$ Nombre de la Actividad: $\\\\$ " title
 " $\\\\[0.1in]$ Fecha de entrega: $\\\\$ " (p (org-read-date nil nil nil "Fecha de entrega"))
 n ":END:"
 n q
 )

It will only prompt me once. Why is that the case?

You should use (p ...) for prompts. Other forms are for evaluation only in order to automatically compute text.
