problems with setting Other fields

[jokosan]

In Umbraco 10.6, the "Other fields" feature is not functioning correctly. When clicking on a field after saving, the chosen fields reset. The problem was temporarily resolved with some additional steps:

Open "Info" for a chosen page and click on "Document Type."
In "Document Type," go to "SEO settings," make any change, click "Save," then remove your change, and click "Save & Close."
Then, select the desired option on the page and save & publish the page.
Could you advise how to fix this issue permanently?
