 ## Unreleased
 
+- The `utils/fix-field-layout-uids` command now checks for duplicate top-level field layout UUIDs. ([#18193](https://github.com/craftcms/cms/pull/18193))
 - Fixed a bug where all plugin settings were being saved to the project config, rather than just posted settings. ([craftcms/commerce#4006](https://github.com/craftcms/commerce/issues/4006))
 - Fixed a bug where custom selects could be positioned incorrectly after the window was resized. ([#18179](https://github.com/craftcms/cms/issues/18179))
