One of the oddest things I've seen on SharePoint to date...
I have a list which was created from a template with a few workflows already attached to it. After I created the list, I deleted all of the workflows and created an entirely separate one in SPD.
Normally, SPD would put in the workflow column so you can see the progress, history log, etc. Well, it actually put two columns in, and if I display one column, the other is displayed as well. In the view settings, it shows two instances of the column. Even if I uncheck one, it will display both.
Is this a common problem? Any easy fixes?
