"wall opening" not deleting not edit

[Anonymous]

I made some wall openings Not by using the profile editor, but by using “wall opening” (next to ‘attached top’). I need to adjust them, but they are not selectable? I am in a section view trying to edit or even delete to then use profile edit. But I cannot select them. In an older post, someone noted go in 3D view which I did and isolate wall but opens will not tab through?

I would NOT like to have to recreate this wall will object hanging on it.

Thank you for any help

works if I have "all on" I suspect when I isolated WALL in view—that  the opening is on an “off” category

Rectangular Wall Openings do not belong to any particular category.  But when you isolating the wall category then every other thing, categories or non-categories, is hidden.  That is one of the many disadvantages of Wall Opening tool.  I would rather use a loadable door/window family or an in-place family.
