You need to control if the section is required. For example: profile.description is a optional field, if we don't have information we shouldn't display that section. The same with other ones.

Hello 😃 ! using the data from "manfred-schema.model.ts", these are all the conditions that have been checked and modified:

1) experience is an optional field (experienceCollection in the section.part.js)

• job.description move into roles condition, now includes the rest of the code in this condition
• startDate is a required field, it has returned to the original code 2) hardSkills (knowledge) is an optional field (hardSkillsCollection in the section.part.js) 3) languages (knowledge) is an optional field (languageCollection in the section.part.js)
• language.level is an optional field 4) profile?.description (aboutMe) is an optional field (profile in the section.part.js) 5) profile?.relevantLinks (aboutMe) is an optional field (profile in the section.part.js) 6) softSkills (knowledge) is an optional field (softSkillsCollection in the section.part.js) 7) studies (knowledge) is an optional field (studiesCollection in the section.part.js)
• The field study?.startDate is a required field, condition modified to ask for study?.finishDate because it is an optional field
