SQL Server Management Studio Not Allowing Table Changes That Require A Table To Be Dropped

I was doing some work with a custom table yesterday and at one point needed to make a change to the table layout via SQL Server Management Studio. However, when I tried, I got the below error message;

' title='Saving changes is not permitted. The changes you have made require the following tables to be dropped and re-created. You have either made changes to a table that can't be re-created or enabled the option Prevent saving changes that require the table to be re-created.' />

I’d renamed a column which is why the table needed to be dropped and re-created but this should have been possible (I’ve definitely done this before); I also hadn’t changed any options is SQL Server Management Studio.

The option Prevent saving changes that require table re-creation (Tools >> Options >> Designers >> Table and Database Designers) is in the Options dialog;

It was indeed enabled but I hadn’t been into the Options since loading SQL so being prevented from saving changes which require tables to be dropped and re-created is actually the default option. I unchecked the option and tried resaving the changes to the table; this time successfully.
