Looks like you need to delete the swap partition between them. If you are using it you can turn it off in the os it is being used and then recreate it afterwards.

Edit - I see now that the partition you are talking about is not even pictured in the image at the top and there are lots more partitions between them. While I think it is possible to move partitions I can’t tell you how. The drive is a bit of a mess though, maybe consider getting another one and moving some of the stuff off it?
