Text boxes can't be deleted

[chriscavsib]

Hi all
Not a formula question but something weird..

I have a very large spreadsheet which I've been working on for some time. Last week, I noticed (as I was trying to copy and paste) that there appeared to be text boxes in one particular column. I've tried selecting them and deleting, tried cutting and nothing works. There are no tracked changes on the document and all the other solutions Google has come up with haven't worked.

Has anyone come across this before?

Perhaps there are many stacked on top of each other. Click Home, Find & Select, Selection pane to make finding objects easier.

Thank you very much
