Hub Sites, Team Sites and Site Columns
You need to make sure you create site designs that include things like your content types and site columns. Generally you incorporate the site design when the site is first created/provisioned. However, you should be able to apply site designs after the event via the Site designs option under settings
i.e. choose Settings (cog icon) > Site designs.
If a site design has been applied it should be listed in this area. If not, choose the 'available site designs' link, where you will find a drop down control with a list of your available site designs that you can choose to apply. Note if you haven't created any site designs your list will probably be empty.
For more information see the documentation article - SharePoint site design and site script overview

It's not worth the hassle. I'll just recreate it new like wayyyy back in 2003. Almost 20 years later and this is still a point of contention.
