K2 to Content Migration Plugin question

I found a few bugs:

1. The "radio buttons" extra field doesn't transfer the values ​​in the additional field, e.g., "yes" or "no," and only enters certain values ​​into the #__fields_values ​​database.

2. The "textarea" extra field with the "Use editor" option checked converts to "textarea" when it should be "editor."

3. In K2, the extra field group is assigned in the category. In Joomla Articles, the category is assigned in the extra field. It would be nice if this were automatically completed. A checkbox could be added if someone doesn't want this option.

I have a module about a place in a Spanish-speaking country, but some comments in English appear first, followed by some in Spanish. The module is set to Spanish. How can I make only the Spanish comments appear?

I have over 11k articles that i want to migrate, i am using pro version but on all the tests i made the component does not migrate all articles at once (probably cause a server time out) and the problem is that if you try to migrate again then the k2 items and categories that has already migrate it remigrates again with another alias. That is a problem cause now lets say for k2 category "announcement" have multiple Joomla categories (announcements, announcements-176552940 etc) with different aliases and with each one portion of the items included in the k2 category. I even changed the limit in the controller from 60 to 5 or eve 1 but again the same happened. Is there a way you make the component continue from where it stopped?
