[SOLVED] Android XML: "conflicts with another tag that has the same ID"

I recently deleted a fragment including its layout and viewmodel from my project. (FragmentAddFlight, VmAddFlight, fragment_add_flight.xml)

Surprisingly I am getting these errors:

Remember the file referenced in these error has already been deleted. Why do I get these errors?

I cleaned the project via Build -> clean project. I tried to rebuild the project via the same menu. But the result remains the same.

Does anybody have an idea how to solve this issue?
