Confusing page "Schema Import Configurations"

[signedav]

Users find this page confusing:

How comes that it looks like it looks? The models are "detected" by several ways.

1. Read from the selected local ini file.
2. User selected from the repositories.
3. Parsed from the selected transfer or catalogue files.
4. Depending model of a catalogue referenced in the ilidata.xml of the repositories.
5. Defined as ili2db attribute in the metaconfiguration received from the UsabILIty Hub.

Users are confused.

1. same model is listed multiple times
2. sometimes checked and sometimes unchecked
3. they look like a list of files. where am I know? on file import?

Suggestion to make it simpler (mockup)

1. remove the icon
2. list it only once
3. add grey description why its here
4. tooltip with additional info (where it comes from etc)

Still there is the possibility to uncheck it if not required.

Opinions?
