How to remove the off canvas filter from top menu

I'm sure this something obvious that I'm missing; I'd like to have the off canvas filter in a hook before product loop, I've done this, will tweak CSS later, but it also appears in the top menu. I see how the GP Niche has done this, so I know it's possible, but I can't seem to find where in the settings or code this is achieved.

I don't have off canvas filter set up in any other menu so not sure how it's appearing in the top menu.

I've provided an example of the issue in a bare bones example.

Thanks for your help,
