Added necessary gif and pics.

Would like to show a new error.While Signing up as a volunteer , the city , country and state field has neither dropdowns nor their value gets saved the last screenshot clearly states the blank fields.

I have opened one issue regarding the dropdown but it has not been yet reviewed. If you say I will love to work on both these issues.

Regarding this, Have you migrate the cities light?

I guess yes , because it's working for admin but not for volunteer

In the last pic , it's evident there is a drop down when you try to edit those. But in the start there is not .

I will make migrations once again and will check.

Yes, Please check and confirm here. Thanks

@satya7289 the issue got solved , when i recreated the database and again made migrations!
