Hi, This one is working correctly for me. Could you do a quick test in a brand new file, just to see if it is consistent for you on your machine, or isolated to your particular timeline file? If it is just the one timeline file, the quickest way for me to investigate the issue may be for you to email it to firstname.lastname@example.org Obviously, we will keep the file completely confidential, but I understand it may not always be possible to email such files due to privacy reasons etc, in which case we can try to work it out another way.

After some testing I have found where my problem was. I had used parentheses in my Arc titles and this was what was breaking the filtering. Now I have removed them everything is working as it should.
