no puedo modificar una fila de los grados académicos

estoy tratando de modificar la fecha del título alcanzado, pero no me lo permite el formulario

Hi Juan,

Thanks for reaching out to Jotform Support. Unfortunately, our Spanish Support agents are busy helping other Jotform users at the moment. I'll try to help you in English using Google Translate, but you can reply in whichever language you feel comfortable using. Or, if you'd rather have support in Spanish, let us know and we can have them do that. But, keep in mind that you'd have to wait until they're available again.

Now, let me help you with your question. It seems that you're logged in as a guest user. Is the form shared to you as a form collaborator? Also, If you can share the link to your form, I can check it out and see what’s going on.

Give it a try and let us know how it goes.
