Cleaning up swap issues on Ubuntu Server 20.10

Question spawned from a previous question found here:

Very long startup time on Ubuntu Server (network configuration)

I have two swap partitions mounted in my fstab which seems odd. I'm guessing it's a byproduct of the process of builing a RAID array (maybe I botched something somewhere).

Some relevant logs as suggested by @heynnema:

/etc/fstab:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>

/swap.img   none    swap    sw  0   0

swapon -s:

ls -al /:

free -h:

The output of fdisk -l does not list any swap partitions...
