I’m having an issue where any changes made to layouts in SuiteCRM 7.3.1 don’t appear to save properly. When the save button is clicked it reverts back to its previous layout. Is this a known bug?
I think what you are talking about is a bug. It does update the layout but it does not appear to have been updated in studio. But if you come out and go back in the layout has changed.
Many studio bugs were resolved in SuiteCRM 7.3.2, and are also resolved in the SuiteCRM 7.4 releases. I would recommend that you upgrade and feed back any further issues.
