How to remove incorrectly made triggers from hosts

[xanadu]

Last week I created new discovery triggers for my host:

disk space is less than 10GB

Now it seems that 10GB is a bit too much and I modified the trigger in the discovery rule to be 5GB.
But the discovered rules aren't removed on the hosts. Only the new triggers are added. Only way not to receive the 10GB triggers is to disable them. But that is an immense job..

Is there a way to remove the old, incorrectly made 10GB trigger from the hosts?

Use filter panel to select all unneeded triggers.

Thank you for your reply. But I don't see how.

Can I get a list of all triggers for all servers so I can easily select all the same triggers?

My mistake. No filter function in Configuration -> Hosts -> Triggers. Should think about API.
