Cannot enable Enable National Vulnerability Database mirroring

### Current Behavior

I use helm to install dp on my k8s https://evryfs.github.io/helm-charts/
with 1.5.5

recently i found I cannot enable Enable National Vulnerability Database mirroring,
every time, after I enable it and give the url like "https://nvd.nist.gov/feeds", then click update, it always saying "configuration saved", but if I go other places and come back my change get lost.

### Steps to Reproduce

1. login as admin
2. click administorator
3. click "vulnerability sources"
4. click "National vulnerability database"
5. enable "Enable National Vulnerability Database mirroring
6. put "https://nvd.nist.gov/feeds" in the Nvd Feeds URL
7. click update.
8. refresh the page.

### Expected Behavior

I was expecting the NVD is still enabled and with the Feeds URL there. but everthing back to disabled.
