Please give us a description of what happened.

Go to Dashboard > SEO > Search Appearance > Content Types > Listings
Add custom field keys > Save >
Return to Dashboard
Return to SEO > Search Appearance > Content Types > Listings
No data saved in field
Yoast not able to review custom fields in individual listings

I tried deactivating all plugins except for Yoast SEO, Yoast Premium, Elementor and WooCommerce.

Please describe what you expected to happen and why.

I expected the field keys I entered in SEO > Search Appearance > Content Types > Listings
Add custom field keys > Save >
To save in between sessions, and in between going to another area of the Dashboard and back to SEO > Search Appearance > Content Types > Listings again

I would like Yoast/Yoast Premium/Yoast-ACF-Analysis to be able to recognize and review my custom fields on individual listing posts.

How can we reproduce this behavior?

1. Go to Dashboard > SEO > Search Appearance > Content Types > Listings
   Add custom field keys > Save >
2. Return to Dashboard
3. Return to SEO > Search Appearance > Content Types > Listings
