How to turn off filters in Load Track preset bay?

Possibly a silly mistake,

I thought that if you press the [<< button the ‘clear filters’ button next to the attribute button in the Load Track Preset window, it would turn off any preselected filters?

I am having difficulty finding user saved presets

Open a project make two instrument tracks - leave one blank

Put some data on the other one customise it, give it a name.

Right click on this track save preset

Save it with the memorable name

Go to the blank track, right click select ‘load preset’. Click on the [<< button next to the attribute button .
Type the name into the red panel - no show.

Struggling to understand this
