Multiple empty records created in the contents_props table - Delete ?

[fxv_cms]

Hello

I noticed that for every content page created, 1 record is created in the cms_content table (as I expected) and 6 in the cms_content_props table :

- one with prop_name="content_en"
- one with prop_name="extra3"
- one with prop_name="extra2"
- one with prop_name="extra2"
- one with prop_name="pagedata"
- one with prop_name="target"

even when extra1, extra2, extra3, pagedata and target are not used.
These 5 records have then empty fields except the content_id, type (string) and prop_name.

Does anyone know
1) why these 5 "extra-records" are created instead of having the fields of the cms_content used instead ?
2) if it is possible to delete these empty records with no impact to the navigation for the end-user ?
 

The reason why I would like to delete these "empty records" is avoiding an inflation of records in the table, since I am converting an HTML site with several hundred pages into CMSMS and do this largely via mySql.

By the way, is there a cleaner way to load a batch of HTML pages into CMSMS, instead of modifying directly the tables in the database ?

Thanks

François

Yes but they are create automaticaly if you edit that page, they are the params of a content page
