In the version history, we see that one of our site columns (Boolean type) has a value automatically set after uploading (version 0.1 of item). We have tested this using Graph, drag and drop - we got the same results.
This doesn’t happen to any other site column. We use the same solution for different SharePoint Online sites and this field is always left blank.
Why does this column behave differently than any other Boolean column in our solution? Is there a way to change it?
