Why have my sheet metal bend center lines disappeared?

Fusion 360 seem to have "suddenly" stopped showing me the bend center lines on my sheet metal flat patterns! [Bend extent lines are still visible.]

I do not think this has been caused by me turning off the visibility of the centre lines (which is something you can normally do by toggling the visibility state of the relevant layer in the component browser tree) --- because the row in the browser that would normally hold the centrelines is just missing! (see screengrab). Of course, I may have done something else bad without realising it.

I am using Fusion 360, but looking on the web I found a post from Feb 2020 (or was it 2021, I forget?) where an Inventor user reported the a similar problem. But that post had a not very reassuring autodesk reply saying something slightly self-contradictory, like "We have fixed this in an update, but we will fix it in a future update." To be sure I updated to the most recent Fusion 360, but the problem persists. I am on a mac.

Oops, I attached the screengrab as a PDF, which makes it not easy to see. Here it is as a png:

You did a cut-out on the folded model across the bend. It is indicated in the screen capture below. I corrected this by removing this part of the sketch and which removes down stream features and added them at the end by doing an Unfold before adding the cutout across the bend. NOTE: I did not dimension the cut and fold correctly when I put it back, I just wanted to demonstrate. My model, with wrong dimensions but the right features to bring back the fold centerlines is attached. I do not know if this is a flaw in the application but the help files clearly say to do cutouts "across" bends in an unfolded state.

Thank you - that's a very clear explanation.
