Bootcamp: Your disk could not be restored to a single partition

Hi, I tried removing my windows partition for a reinstall but I got this error message. It suggested that I use disk utility to fix it. However, I do not see my bootcamp partition in disk utility. All that space seems to have disappeared. I tried running first aid but that did not help.

Edit: it is a late -2014 iMac

I checked similar threads but could not find anything. Here is what diskutil list gives me:
