CMS failed to serve some records

Noticed many of my old records created last year suddenly failed to come through in my middleman website, but some of those records did pop up in the website,

When I duplicated these records, some of them appear in the website but some of them are still not.

Not idea what’s going on but really seems the records were corrupted somehow. Need help ASAP.

hello and welcome to Community!

This to me looks like a particular problem either with your middleman-dato gem (are you using the latest version?) or with your project.

Please provide more details on the records that are not working over this form:

If possible access to your repository would be helpful so that we could better reproduce your problem! Thanks!
