Uploading my application to the Microsoft Store

I uploaded the package as instructed and completed the various required sections, but the system continues to block me in two sections, marking them as "incomplete."

"Submission options"

I entered justifications for the "Restricted capabilities" section.

My app doesn't require a login or password. I left the "Additional Testing Information" section blank, but it won't let me proceed.

I tried filling it in with some information, but it won't let me proceed.

The "Store listings" section also gives me problems.

The system defaults to English in the "Languages ​​supported in packages" subsection, but my app is only in Italian.

I added Italian as a language in the "Additional Store listing languages" subsection.

In any case, it won't let me proceed, and the section is marked as incomplete.

I don't know what else to do.

I'm going crazy.
