Aux trill (no note in bracket)

I have issue with aux trill notes. It doesn’t show up automatically. I have to right-click on brackets and choose default notehead then it’s ok.
I’ve never had this problem before. It happened today. Please help!

Hi Wojtek, welcome to the forum. Have you modified any of your notehead sets?

Thank you for greeting!
I added three notehead sets, but default is reverted to factory.

Ok! I got this! I had to hit the second ‘revert’ inside the window. Now it works!
Thank you Dan for pointing me the way out.
All the best.
