The following libraries were not found

Always if I open ‘schematic’ the following ‘text box’ is coming up:

The following libraries were not found:

  • transistors.lib
  • conn.lib
  • 74xx.lib
  • cmos4000.lib
  • display.lib
  • valves.lib

There are no such entries in ‘schematic library table’.
How can I remove these libraries?
Thanks

You are using nightlies! (This means you are a bug tester. Welcome on board)

We already started with transferring some libs to the new lib names.
Either check out the libs tagged as 4.0.7 to have your libs setup equal to the 4.0.7 release or update the list of loaded libs in each of your projects. (eeschema->preferences->component libraries)
