Partition won't delete

I am on macOS High Sierra version 10.13.6.

I had used bootcamp assistant in the past to partition my macOS to split to have windows and it worked. I then changed my mind and wanted more size allocated to it so I restored the partition and did it again but while it was partitioning I quit boot camp assistant because I thought it was stuck.


Now there is an untitled partition that I can't delete. Any help is appreciated. Thanks.

iMac 27″ 5K, macOS 10.13

It's not supported to resize BOOTCAMP partitions. The easiest way to fix this is to back up your Mac with Time Machine, then erase it and restore from the backup.
