How to delete things in "My filter" inside"Avast Adblock Advanced Settings"?

I blocked Facebook topic item accidentally, I am looking for a way to delete that rules in"My filter" inside"Avast Adblock Advanced Settings.
Is there any possible way to do that? Even it might needs to clear rules in My filter, it’s okay.
I can’t find any button like that(clear, disable, delete).
Help me please :cry:

Hi brother12355,

I’m sorry, the button is to remove the filter is there - but it is invisible (it is an issue that our developers are working on resolving). Please take a look at this message for instructions on how to remove the filter: https://forum.avast.com/index.php?topic=226743.msg1503423#msg1503423

Thanks for the help! I deleted successfully! ;D
