Can't Remove Free Space Partition! please help

13" Macbook Air 2017 128gb

Problem occurred when i erased bootcamp partition through disk utility as a way to uninstall windows 10.

This photo shows what the "Free Space" partition I'm trying to remove looks like in disk utility

And this is what happens when I try to delete the "Free space" through disk utility

When I run diskutil list in terminal -

/dev/disk0 (internal, physical):

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *121.3 GB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_APFS Container disk1 73.0 GB disk0s2

/dev/disk1 (synthesized):

#: TYPE NAME SIZE IDENTIFIER

0: APFS Container Scheme - +73.0 GB disk1

Physical Store disk0s2

1: APFS Volume Macintosh HD 47.3 GB disk1s1

2: APFS Volume Preboot 20.3 MB disk1s2

All help is appreciated!
