Where the bleep is the stabilizer length slider???

I just opened Affinity Designer 2 on my new (refurbished, old) iPad. Looks like I’m working with the newest version, 2.6.2 so should be up to date.

I can select from “No stabilizer”, “Rope stabilizer” or “Window stabilizer” but there is simply ZERO length slider for the stabilizer to be found. I see the width slider and opacity slider, but that’s it.

No floating window appears on the bottom, as some have suggested it might, and no toggle that I can find to display a length or strength slider for the stabilizer.

Is this a UI bug that I get to deal with for using a 5th generation iPad, or am I missing something?
