Cannot shift objects off sheet when hiding columns

I'm trying to hide all the columns to the right of a table, but the sheet in the workbook is not allowing it. I've selected all the columns to the right and deleted them, cleared them, checked that all objects are displayed in the excel options, and that no comments are in the cells. The sheet is also unprotected.

There's literally nothing in the cells in the columns I want to hide and yet I can't hide them.

I can't share the workbook due to confidential information, but has anyone else experienced this? Excel 2013

What do you mean when you say that the workbook is not allowing it? Are you getting an error?

Maybe clear any confidential data then upload the workbook for us to take a look.

Never mind, I found an ActiveX object someone had hidden in the sheet https://www.excelforum.com/images/smilies/mad.gif
