When generating the pdf it does not show the information sometimes.

Hi, I have a long form with several checkbox options and groups with conditional fields. For some reason when generating the pdf it does not load the form values in some fields, sometimes.
All the information is saved in the DB and when I send the email and attach the CSV of the data, the data is in the CSV but is not reflected in the PDF.

Form extract:

SELECCIó ACOLLIDA
[checkbox BON_DIA_CHK use_label_element exclusive "ESPORADIC BON DIA" "BON DIA (08:30h - 09:00h)" "BON DIA (07:45h - 09:00h)"]




[checkbox BONA_TARDA_CHK use_label_element exclusive "ESPORADIC BONA TARDA" "BONA TARDA (16:30h - 17:00h)"]
