I know this is a really simple task and I have done it a thousand times and it worked every time, but I cannot rename a list via powershell anymore.
$List = $web.Lists["mylist"]
$List.Title = "newtitle"
When I check the Title in a seperate powershell window the name is correct. Also if I check the List in SharePoint Manager2013 the Title is the new one.
But in the GUI it stays the same. I tried reloading the page and clearing the cache and everything, but it does not change.
What can be the problem here?
