Capture polygon, after several points are deleted in the application, ask: will I have an error in the template?

1. What is the issue? Please be detailed.

When users arrive at the group to capture information by polygons, when filling in a number of points the form saves them but when continuing with the survey, it immediately deletes them, and does not allow me to retrieve the information of the points of the previously captured polygon. PS: I will have an error in the template of the form, that is why I attach it, I am attentive to the suggestions

4. Upload any forms or screenshots you can share publicly below.

Does the calculation close the polygon? See

A series of points that form a closed polygon. Identical to geotrace except that the first and last point are always the same and at least 3 points are required.
