Today for some reason I was unable to edit and save in a document library of mine when I changed items in any column. I found that a column titled "Description" was now there (was not there before) and it was requiring information. I didn't need this column as I already have one with that title so I tried to make it optional and just hide the column but that did not work. I then found that I had 3 columns all labeled Description and deleted the two extra that I did not need. However, even though I've deleted the column that was giving an error I am still receiving the red exclamation mark and can not edit anything in my list.
I went to the recycle bin, nothing was in there but documents, which makes sense. I restored the library to yesterday but that didn't work. I don't know what else to do and need the option to edit my list.
