I have an instance of SharePoint online. After creating a number of similar document libraries, I eventually created a site column, to save some time, and to keep data consistent.
I have a Site column called "Year" that is a multiple choice field with choices "2015-2016,2016-2017, 2017-2018, 2018-2019,etc".
Recently I have noticed, that the Year field is now appearing in all the libraries, whether I have put it there or not. What's more troubling, is for the libraries that existed before I created the site column, there are now 2 columns with exactly the same name.
- Is this normal for site columns?
- If I delete the site column, and there are document libraries that are actually using that field, will they disappear? (My guess is no, but it could impact things negatively if I were to do that, at the moment, I'm manually deleting the second column that is unused.)
Any enlightenment would be appreciated.
