Sharepoint metadata and Word

[FrodeH]

I have a sharepoint library with several columns for metadata. These are NOT mandatory fields. BUT when i edit the document Word seems to think they are mandatory. Anyone seen this?

Could you please post a screenshot of what you see?

@Juan Carlos González Martín first screenshot from word - second from sharepoint

Steps to reproduce

1. add custom SP property to document

2. fill in anything in field 

3. remove "anything" from field

4. observe field error message

A temp fix is to go to properties in word and add and remove text from the field until the red warning box goes away.
