I've stumbled upon an issue with one of my SharePoint lists that is preventing me from editing the list's View, or saving the current view under a new name. This is the screen I get when I click on "edit view" from the view drop-down: (Error reads: "Sorry, something went wrong// An unexpected error has occured.// Correlation ID: fa9e149f-90e7-9000-89f1-9d7048dbb1dc")
And this is the error I get when trying to save the current view under a new name:
(Error reads: "Column 'Listapprovaldateby_x005b_jobtitl0' does not exist. It may have been deleted by another user.")
At one point I had two "approval" columns in my list. One was titled "List Approval Date by [ job title 1 ]", and the other titled "List Approval Date by [ job title 2 ]". I then decided that two separate columns were not needed, so I deleted "List Approval Date by [ job title 2 ]" and renamed the first column to "List Approval Date by Both Job Titles." After deleting one and renaming the other, this issue began occurring.
My guess is that I've somehow left a "phantom column" on this list but have no access to it, so SharePoint freaks out whenever it tries to look at a view. But I have no idea of how to clear out the phantom or how to save/edit the view otherwise.
(note: as far as i can tell, no other functions on the list or site have been affected apart from editing the view of this particular list. Also there is no evidence of the "phantom" column anywhere other than this error message.)
Any help or idea is appreciated.
