There is any way to remove the "not relevant" fixlets and tasks

There is any way to remove the “not relevant” fixlets and tasks, where 0 relevant computers.
I am master operator but remove tab is disabled for me. more than 1.6lacs fixlets and tasks are not relevant in my environment and once you click on “not-relevant” tab console get stuck. please suggest if it is possible, if yes then what will be the impact?

You can’t edit or delete the content of external sites - and if you could, what would happen when, at some point in the future, those fixlets do become applicable on some clients?

The ‘Show Non-Relevant Content’ button toggles on and off and does what you want.

Also, be wary of habitually running the console as MO.
