Unable to create or import Scan configs

Hi all,

I am running Kali Linux, and have performed the installations steps.
This is currently what I have encountered.

Fired up and was not able to create or import scan config with the error message.
Failed to find config ‘daba56c8-73ec-11df-a475-002264764cea’
“There is indeed this file in the directory”

sudo -u _gvm greenbone-feed-sync --type GVMD_DATA [THIS IS OK]

sudo -u _gvm gvmd --rebuild-gvmd-data=all [SHOWED THE FOLLOWING ERROR]
Failed to rebuild gvmd data: NVTs must be available while rebuilding configs.

gvmd --modify-setting 78eceaec-3385-11ea-b237-28d24461215b --value gvmd --get-users --verbose | grep admin | awk '{print $2}' [SHOWED THE FOLLOWING ERROR]
(gvmd:101575): md main-CRITICAL **: 05:43:27.419: gvmd: g_option_context_parse: Missing argument for --value

What should I do next?
I have tried scouring the internet to deal with this specific error, seems like I am unable to find the solution.

Hope a kind soul is able to assist me in this.
Thanks in advance!

Also, let me know what you guys require, I am most than willing to share any other error messages etc.
