Using enterprise custom fields

Hello

I created an enterprise resource field called Limit_hours as shown below where I could enter max hours a resource could work.

When I try to edit the resource in pwa, I am able to add a value which is saved

But I am not able to i. Add this field as a column in resource centre.

ii. Add this field as a column in resource sheet in project professional.

Please advise on why this is happening.

Thanks
