Here is a more permanent solution provided by the Arturia Helpdesk:
1- Quit Logic Pro X if it is running.
2- In the Finder, choose "Go to Folder" from the Go menu.
3- Type ~/Library/Preferences in the field and click Go.
4- Remove the following files from the Preferences folder:
com.apple.logic.pro.cs
com.apple.logic10.LSSharedFileList
com.apple.logic10.plist
- Note that if you've programmed any custom key commands, this will reset them to the defaults. You might want to export your custom key commands before performing this step. Learn how to Browse, import, and save key commands.
5- If you upgraded from an earlier version of Logic Pro, also remove the "com.apple.logic.pro" file.
6- Then restart the computer.
