Downloaded the CMS folder from the server and checked the meta data… Is the problem the brackets? why are they there?

For some reason - I checked all the other podcast files - no brackets… Must be that - How did it get added? ---

@ben seems to be adding brackets on the meta data in CMS V2 ![Screenshot 2026-06-05 at 4.03.27 PM](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/8/4/845bdde741efc9dceee7df499d3ea0ac02449646.png) ![Screenshot 2026-06-05 at 4.03.37 PM](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/2/6/26a13daba23fd87ba9bf0cd9428b619f052e2e2c.png) ---

The field type in the online CMS is set to array, you need to switch it to resource for that folder/collection. ![CleanShot 2026-06-05 at 10 .34.29@2x](https://europe1.discourse-cdn.com/flex005/uploads/realmacsoftware1/original/3X/3/e/3ef2f4aed0a21198f9b17676eb90f690628fe5c4.png) ---

quick update here to say we’ve fixed the underlying cause of those mystery square brackets 🙂 The Online Editor’s frontmatter serialiser could turn a field into an array under certain conditions (emptying a field and refilling it was the usual trigger), and one corrupted file could then flip the detected field type for the whole folder — which is why a single podcast post had brackets when the rest didn’t. From the next Elements 3 update, fields always save as plain strings, and re-saving an affected post in the editor cleans up any brackets already there. No more downloading the CMS folder to hunt for them 😃
